Canadian engineer here. Although we use the metric system in principle, in reality we use feet and inches for everything. There are lots of benefits to using base 12 for measurements.
The number 12 has six factors, which are 1, 2, 3, 4, 6, and 12. It is the smallest number to have six factors, the largest number to have at least half of the numbers below it as divisors, and is only slightly larger than 10. (The numbers 18 and 20 also have six factors but are much larger.) Ten, in contrast, only has four factors, which are 1, 2, 5, and 10.
I get the Europeans hate it though because only the people who live near Chernobyl can count to 12 on their fingers.





5/32 is 10/64, maybe you can figure it out from there.
