> Inches/feet being base 12 divides better into thirds and fourths, which is very useful in construction.

all of the math normal people use in everyday life happens in base 10.

"it's easy because it's base 12" is an absolutely ludicrous idea.

what's 7'5" divided by 3? divided by 4?

what happens if you need to divide by 5?

and sure, there are various mental math tricks you can learn to make this easier...or you could just use the metric system.

7'5" is 226cm. that's a normal, boring, everyday, base 10 integer.

you don't need to learn a special set of "mental math for base 12" tricks. instead you can re-use the same mental math tricks you use for every other base 10 number.
