Someone was talking about decimal time where the second is shortened by
about 15% allowing 100 secs/minute, 100 minutes/hr, 10 hr/day.

I think the utility of this is limited and it would cause a lot of changes
in society. We presently have a large number of convenient time increments
which would not be so convenient in the new system.

First, the hour would be 2.4 times longer leaving us with no convenient unit
about the same length of time as the hour. The closest would be the
quad-deci-hour which would be 0.96 old hours. The deci-hour would be pretty
convenient about 4% shorter than a quarter hour. The old half hour would
now be about a fifth of a new hour, so we could call it a "fifth" which
might become confused with a non-metric liquor measure, a fifth of a gallon
which has since become 750 ml in metric.

The inconvenience would come from the need to totally recalibrate every type
of measurement we use that considers time... speed limits, work days, time
zones... Would we extend this change to measurements of angles which often
are done in degrees, minutes, seconds?

How would we adjust the work day? Do we go to 3 hour work days which would
be about 7.2 old hours? Shift work would have to split hours to get three
shifts while some businesses that use two 12 old hour shifts would hum along
just fine with 5 new hour shifts. Many businesses opening at 9 AM would now
open at 4:00 (I assume we would just count 0 to 9 hours rather than the
annoying AM/PM thing), folks would take a lunch break at 5:00 and banks
would close around 6:00 while retail would remain open until 9:00 or 9:50
(hmmm, that is still about the same).

The minutes gets pretty whacked gaining 26.4 old seconds. So "give me a
minute" becomes a quarter more weighty of a request. The original pulse was
conceived to match the human pulse so our normal pulse rate will become 86
bpm instead of 60 bpm.

In science the changes would be enormous. With a redefinition of the second
every time related measurement would have to change including many in EE
such as capacitance/charge/current, heck, the definition of the
gravitational constant and even the speed of light would have to change.
Every text book would change and every instrument. This would create so
much confusion that we really would need new names for the second, minute
and hour.

This could go on all day (the one measurement that doesn't change) with a
huge list of changes we will have to make and the many adaptations we as a
society would need to accommodate. Then, in the end, we would still have
leap years.

I don't remember that "people just would not go for it". I don't recall

had a partnership with Canada to change together and had a multi-step
program. We completed the first two or three steps and quit. That's why
metric is taught today in schools, it was part of step two or three. When
we had to take a step that would actually change something (I think it was
highway signs) we told Canada to go on without us and we'd catch up later...
*much* later.

I can't believe that even today we still use English units in many
engineering fields. Mechanical engineers often use inches and feet. God
knows what civil engineers use, probably rods. It was just recently that I
learned the acre comes from 160 square rods.

Actually I just looked it up and the acre was defined as 1 chain by 1
furlong while a rod is a quarter of a chain. A chain is 0.1 furlong, so
they are all a related system of measurement.

Well you and I remember differently. I was involved in the teaching of
the metric system to the people of the USA. There was great resistance
and money for the project soon got thin. When I studied engineering in
the 70's we used the metric system exclusively. We didn't call it SI, it
was just the way the scientific community did it.

What teaching were you involved in? I assume it was companies asking you to
educate employees? That is not related to the government. It also has
nothing to do with the "resistance" from the average person. No one was
overly enthusiastic about it since it was a big change, but people were
willing to go with the flow. Mostly they just didn't understand it as there
had been only notification that it would happen and the education was only
in the schools. I believe it was industry that resisted the change much to
our detriment over the decades.

I don't know what you mean about metric not being "SI". I didn't know
diddly about metric until I was in college (before the conversion program
started) and was taught the SI system. I believe prior to SI there was a
metric system that had a few units that were different from today's SI by
some powers of 10. CGS and dynes come to mind.

Mpffffff... what is unique about time-keeping as-practiced? It is base-12. Meaning that its 24-hour days are nicely divisible by more prime numbers than if it were base-10. It also goes nicely with 360 degrees, and such. It is something that entire world agrees to - one of the very few things.

If I may interject:
A lot of years ago I was at a party. I was with a small group of people
and I brought up the topic of Metric Time. I said it as if I really
knew about it and that it was reported on the nightly news by Tom Brokaw
the night before. I said the certain part of Canada had all ready
switched over.

I said it as a joke but did not say that it was. Everyone was 'oh and
'aw about it and swallowed hook, line and sinker. I walked away from
the group and moved else were, snickering all the way.

About 15 minutes later, I got a tap on the shoulder. I turned and faced
a guy that was in that previous group. He had a serious look of
embarrassment and irritation. He said "Metric Time?? Really??" I just
smiled and said "Got Cha". And we had a good laugh.

Actually still laughing today. Since this post put me back to the a very
funny moment in time.

Thanks for the memories.

During the time of the pyramids and pharaohs, the Egyptian calendar had 5 days "out of time" at the beginning of the year, then 12 months of 30 days each.

That still makes more sense than what we do now.

If we did that now, the politicians will call those tax-free days, with
the remainder being taxed at 100%.

Something like the 0 and 00 on American Roulette wheels?

Keep in mind that the 'modern' calendar was the creation of a religious institution to keep the calendar from 'slipping' and entirely for religious purposes. Islam uses a lunar calendar and slips by about 10 days each year. This is most significant during Ramadan, when fasting is from sunrise to sunset. Makes things a bit hard the further north (or south) one goes when Ramadan falls in the local summer time. But, several other groups, including Buddhists and others use calendars apart from the Gregorian calendar - no surprise there at all.

Here is a cut from a Wiki article of which seems to be my experience also.

"The U.S. Metric Study recommended that the United States implement a

over a decade. Congress passed the Metric Conversion Act of 1975 "to
coordinate and plan the increasing use of the metric system in the
United States". Voluntary conversion was initiated, and the United
States Metric Board (USMB) was established for planning, coordination,
and public education. The public education component led to public

resistance, apathy, and sometimes ridicule."

Not sure what you are talking about. Animal rhythms are related to a daily
cycle, it has nothing to do with "hours".


And it would be necessary to redefine the reference second which is now
related to the cesiuaam atom.It is the international reference like the
meter also related to this atom

The second is defined as vibrations of the cesium atom in the same way the
yard is defined in feet. If we wish to change the definition of the yard to
four feet we do that and are done. Likewise we can change the definition of
the second in the same way to a different number of vibrations of the cesium
atom.

Has anyone pointed out that top posting is hard to reply to?

Instead of redefining time measures, we should use base 12 for our day to

You didn't answer the question about what teaching you did exactly. I don't
know what "That's it" means.

I will rephrase my statement. The resistance to metric was less than the
resistance we have to our current President. No one marched in the streets.
No one filed actions with the Supreme Court. Yeah, people were people and
we had some editorials and a few indicated they had no reason to change,
such as the machine shop I worked with at the time. But they eventually
acquired metric capability anyway.

The "apathy" was the largest component of the response to changing to the
metric system by far. If the government had stayed the course we would have
been converted long ago and all the pain would be behind us.

I wonder why the wikipedia quote doesn't mention the fact that we did the
conversion in cooperation with Canada? Because wikipedia sucks and often is
not 100% accurate. Never use them for any disputed point without looking at
the references.

From the Popular Science web site, "A Gallup poll at the time showed that
45 percent of Americans opposed the switch." That means less than half!

Here is a better reference... from NIST.

https://www.nist.gov/sites/default/f...tric/1136a.pdf

While the Congressional study recommended a coordinated conversion over a
ten year period, Congress made the actual conversion voluntary. Consistent
with the "apathy" part of your statement above, the efforts of the Metric
Board were much ignored and the board was dissolved.

Today metric is a much larger part of our lives and I believe a conversion
would not be resisted and in fact, welcomed by a much larger percentage of
the population. Anyone who works on cars has both types of tools.
Measuring sticks and tapes often are marked in both systems. Goods on store
shelves are already marked in both systems. We are presently primed for the
conversion.

There is some irony in a personal anecdote. I was a contractor with the

I posted this here because I figured the most resistance would come from a
community that has a large interest in keeping things the same. So far no
one has said much about the impact on repair.

Hence the indirect reference to that 35% of Americans who are unable to compute without their fingers. Not only do they want things to stay the same, but they would very much like to roll back the clock by about a century, or two.

coordinate
and plan the increasing use of the metric system in the United States".

Here in Norway, we used to read numbers between 20 and 100 with the

someone spoke. As the phone system made its introduction, the need to
write down long numbers increased, so the problem became more

In 1951, the government decided that we would end the insanity and
convert to the system that the Swedes and English use, where the
digits are read in the same order they are written. Since then, the
school children have been thought the new system, and the state
broadcaster has used the new system exclusively (except quite a few
slip-ups, of course).

There is a clear trend, where the old method is more prevalent among
older people. Even still, people who were born twenty years after the
change was officially made, still often use the old way today.

As you can see, changes take huge amounts of time. Even a small,
simple change like that, after more than 60 years, we are probably not
even half way there.

One morning in the early fifties, a military officer spoke to his
battalion: "As of today, we no longer say four and twenty, but two and
forty". He was simply so set in his ways that he was unable to break
free of them, even when he tried.

As I mentioned in another post, we keep the second, the day and the

much resistance at all. I think the "resistance" was at other levels.

Yep. At the time (about 1975), I was working for a company that tried
to switch to metric. This was aided by having the drafting manager
and mechanical designer also serving on the metric conversion council
(or whatever it was called). At one point, we started sending metric
fabrication drawings to various vendors. They were immediately
returned. The problem wasn't understanding the new metric way of
doing things, it was that they would need to replace all their English
lead screws, measurement instruments, gauges blocks, programming, etc
before they could cut metal. They also claimed that they needed
considerable staff training to handle the change (because someone
tried to simultaneously switch to true position dimentioning). We
would need to wait until the shops converted before we could orders
parts in metric.

So, we went back to English units and waited for the "inevitable"
conversion that never happened. It seems that most of the other
customers followed the same pattern. They tried metric, failed, and
went back to English. So, we asked the various fab shops why the
delay? They answered that since everyone seemed to be going back to
using English measurements, they must have run into some problem with
metric. Therefore, the fab shop saw no reason to convert. After
getting approximately the same story from ALL our vendors, we gave up
in disgust.

"Why hasn't the U.S. adopted the metric system?"
http://www.popsci.com/why-hasnt-us-adopted-metric-system

The idea of decimal time has been around for centuries:
https://en.wikipedia.org/wiki/Decimal_time
The big problem is that time, astronomical, and navigational units
that are based on nautical miles, degrees, minutes, seconds, will end
up with some rather odd looking numbers. Right now, 1 degree is equal
to 60 nautical miles at the equator. It's too hot right now to think
about what decimal time would do to all those. Of course, we could
make things look better by switching from 360 degrees per circle, to
400 gradians per circle:
https://en.wikipedia.org/wiki/Gradian
When in doubt, change everything.

Everything that deals with time will need to be tweaked. That's going
to be a problem since we have many ways to keep accurate time:
http://leapsecond.com/java/gpsclock.htm
Notice the difference in seconds. Some smartphone vendors are still
having problems keeping accurate time:
http://802.11junk.com/jeffl/crud/GPS-vs-UTC.jpg
More ways to keep time, all of which will need to be decimalized or
maybe decimated:
http://tycho.usno.navy.mil/systime.html

This is what happened when most everyone assumed that NASA was totally
metric, but wasn't:
http://www.cnn.com/TECH/space/9909/30/mars.metric.02/
I suspect that a decimal time change will have similar transition
problems.

Why don't you just declare that the ratio of the circumference to the
diameter of a circle is exactly 3.0 instead of 3.14159...? I think it
would be easier than changing to decimal time.

You need to do a bit more than say, "it will all work out". Sounds like a
steaming pile of crap to me. The calendar will be crap no matter what you
do because there is no connection between the day and the year. We are
using a crap system because there is no such thing as a good one. Units
less than a day are invented and can be changed at will. But we don't have

Excellent.

Not a problem. Just put a flat spot (chord) somewhere on the
circumference. That will shorten the circumference sufficiently so
that the ratio equals exactly 3.0. Please feel free to name such a
flattened circle in my honor. The newly established Bureau of
Decimation should then declare that the official US circle will have a

I think the utility of this is limited and it would cause a lot of
changes
in society. We presently have a large number of convenient time
increments which would not be so convenient in the new system.

First, the hour would be 2.4 times longer leaving us with no convenient
unit about the same length of time as the hour. The closest would be
the
quad-deci-hour which would be 0.96 old hours. The deci-hour would be
pretty convenient about 4% shorter than a quarter hour. The old half
hour
would now be about a fifth of a new hour, so we could call it a "fifth"
which might become confused with a non-metric liquor measure, a fifth
of a
gallon which has since become 750 ml in metric.

The inconvenience would come from the need to totally recalibrate every
type of measurement we use that considers time... speed limits, work
days,
time zones... Would we extend this change to measurements of angles
which
often are done in degrees, minutes, seconds?

How would we adjust the work day? Do we go to 3 hour work days which
would be about 7.2 old hours? Shift work would have to split hours
to get
three shifts while some businesses that use two 12 old hour shifts would
hum along just fine with 5 new hour shifts. Many businesses opening
at 9
AM would now open at 4:00 (I assume we would just count 0 to 9 hours
rather than the annoying AM/PM thing), folks would take a lunch break at
5:00 and banks would close around 6:00 while retail would remain open
until 9:00 or 9:50 (hmmm, that is still about the same).

The minutes gets pretty whacked gaining 26.4 old seconds. So "give me a
minute" becomes a quarter more weighty of a request. The original pulse
was conceived to match the human pulse so our normal pulse rate will
become 86 bpm instead of 60 bpm.

In science the changes would be enormous. With a redefinition of the
second every time related measurement would have to change including
many
in EE such as capacitance/charge/current, heck, the definition of the
gravitational constant and even the speed of light would have to change.
Every text book would change and every instrument. This would create so
much confusion that we really would need new names for the second,
minute
and hour.

This could go on all day (the one measurement that doesn't change)
with a
huge list of changes we will have to make and the many adaptations we
as a
society would need to accommodate. Then, in the end, we would still
have
leap years.

Anyone old enough may remember when the USA tried to go metric. The
people just would not go for it and it was abandoned.

I don't remember that "people just would not go for it". I don't recall
much resistance at all. I think the "resistance" was at other levels.

We had little resistance here in Australia too, and plenty of people
who would "not have gone with it". But it was mandated; all aspects of
industry and commerce were evaluated and placed on a time-line. By
a certain date, all green-grocers were required to display prices in
both pounds and kilograms. Some time later, prices had to be charged
by the kilogram. Some time after that, it became illegal to display
prices in pounds. Etc... and so for every part of life, on a schedule
that was planned ahead to assist people in learning the new system.
It was not just recommended as "a good idea".

My understanding is that "the land of the free"(*) failed because they
did not make it mandatory.

We are dividing and multiplying by 10, which is much easier to
understand and to do calculation with.

Years ago I went down to the office post room to buy a few stamps. They
were, IIRC, 19 pence at the time. Thinking the young girl at the counter
would tear off a 3x3 block for me I asked for 9 stamps. Her face fell
with panic at the prospect of asking me for the money! So I took pity on
her and changed my request for ten stamps. That didn't help her...
