How much does 12.34 gallons of water weight?

My point exactly. You constantly have to deal with those stupid fractions and decimals in metric system all the time.

Also - weight and volume relations have mostly scientific relevance. Not joe schmoe putting up out some drywall, or proportion door and window sizes.

It's not that you can't use metric system. It's just worse for a lot of day2day.

NO, in metric, I've never dealt with fractions.

It is ALL DECIMAL, which is the point.

It is in the "English" system that you have to deal with the fractions: the board is 8 feet 1 and 23/32 inches long. Now how long will it be when you cut off 5 3/8 inches from that?

If you can't more quickly subtract 137mm from 2482mm, you are either extremely unusual or insincere.

Exactly. Another example:

How many feet is 74 inches? How many meters is 1234cm?

(How long did it take for you to do that math in each case?)

6ft 2inch.

So easy. So clean.

1234cm is the dumbest measurement ever. Once you find yourself working with those, you are either a scientist or you have adapted to the machine rather than have the machine adapt to you.

You didn't actually do the test.

It would still take you longer in your head to come up with 6ft 2inches (which is the wrong answer, btw, the right answer is 6.167 ft.), than it would to come up with 1.234 meters.

This is a super weird comment for a programming-centric forum.
