Nope, a lot of consumer/general-public stuff is in freedom units (we buy milk in gallons but soda in liters, for example), but science is all metric and engineering is mostly metric (the exception is civil engineering).
Speaking of which, that’s not as different from the rest of the world as you might think: ever wonder why 13mm is a suspiciously common size for things like bolt heads and plywood thicknesses? It’s because they’re secretly 1/2"!
I thought everything is done in freedom units over there.
