Then remeasure. You will find that:
- your block is 152mm long.

- you want a 6mm border at each end.

No he doesn't, he wants 1/4" and 6mm doesn't equal that. Close but
no cigar, so much for metric unless you can measure 6.35mm on that
tape

Do you *really* think that 0.35 millimeters (less than 14
thousandths of an inch) is going to be noticeable? Or are you just
trying to be argumentative?

Had enough of that from SWMBO this past week, don't need it from you
too.

Just pointing out that metric isn't the be-all and end-all

No, but it sure makes the calculations a LOT easier. Reduces the risk
of error, too, because you're always adding either integers or
decimals -- not mixed fractions.

Sure. Tell that to the group that engineered the Hubble Space Telescope
where confusion over metric/proper measurements resulting in the launch of
an almost worthless instrument.

Huh? What did MKS/FPS have to do with Hubble's mirror shape?

And consider these two standards:

"Meter = 1/10,000,000 of the distance between the North Pole and the Equator
measured along the Prime Meridian." (Alternative definition: "1,650,763.73
wavelengths of the orange-red emission line in the electromagnetic spectrum
of the krypton-86 atom in a vacuum.")

vs

"A pint's a pound the world around."

Strawman. An inch is defined as 2.54cm.

Now I ask you, which is more practical for your average woodworker?

The one the tools use. The problem is that we now have both. I can work with
either but where both is required is where the mistakes are made.
