People often say something is 1 and a half meters long. I don't understand how people can work with inch measurements. How do you divide 7"3/8 by 5? This seems a major pain.

One and a half seems natural. What about something like a quarter meter? I guess that just becomes some number of centimeters?

Same way I divide 4.7625 cm by 5. With a calculator.

25, yes. It's not too hard to do the math.

That's roughly 0.95 right by intuition, but (7"3/8) / 5 doesn't come easy to me.

You multiply 7* 8 then add 3 and put that number over 8* 5, resulting in 59/40, roughly 1.5”.
