I think the bigger one is the construction industry.
2"x4" studs. 4’x8’ plywood. 16" O.C.
Changing to 44x95, 1219x2438, 406 O.C doesn’t make a whole lot of sense. We could switch over to the metric equivalents (like 1250x1250 or 600 O.C.), but that would mean switching out machinery and would break a lot of standards.
