> "is it better in day to day life"

Speak to a carpenter or construction worker from any country with the metric system. Measure anything by simple powers of ten and simple decimal shifts makes life so much easier. Quick, what is half of a yard-length beam less 12 1/16"?

Assuming you mean (3 ft / 2) - 12 1/16 inches, it's about 6 inches, which is probably the accuracy you need. But it's exactly 5 15/16 inches, which is also easy to do in your head. Carpenters do it all the time, and even a doctor can.

My head did 36" divided by 2, so 18", minus 12 1/16", so 5 and 15/16". That is harder than working with quarters or fifths of meters, but easier than thirds or sixths of meters.

I don't know which is better. Considering how nothing stops you from doing decimal inches or fractional meters, but people rarely do that, both ways seem fine.

		33.3 cm is easy to measure out, and 99.9 cm is exactly 1 mm short of 1 meter, well within tolerances for carpentry. Narrower than the mark left by your pencil. But also like, we have calculators…
