Confronted by resistor marking 75B translates as 5K9, anyone have an
approximate ie 10 percent conversion technique?
to avoid table lookup, eg

add 100 to the 0. ones
100 up to 800 multiply number by 7
add 100 to 8. and 9.
(I always confuse grey and white designations anyway)

A suffix =x1 ..... E= x10000 is straightforward
S for (S)ilver /100
R for o(R) for gold for /10
for the multipliers is the best I could come up with

for
add 100 to 8. and 9.

read
add 100 to 8. and 9. ones after multiplying by 7

How about ...

100 x 10^(nn / 100)

I don't have a brain the size of a planet, mentally multiplying and adding
integres
is about my limit.

I would think that most people would have a calculator handy in their
workshop. Alternatively, why not just print out the chart, laminate
it, and hang it on your wall?
