while this may seem elementary to you, construction requires a lot of tricks that are based on the old system and not the metric system
for instance all studs in a building are spaced 14.5 inches apart which allows for a load every 16 inches. (2x4 boards are 1.5 inches wide so you have 3/4 inch compensation between the board loads).
This is just 1 small thing, but imagine having to rework every blueprint for every house in America.
It's just 1 example, but it is a HUGE undertaking.
