As opposed imperial constants? How is a foot standardized anyway? I suspect most manufactures rely on SI metrics for that.

- tialaramex 8y agoThere are no other standards. Metrology is expensive and doing it over again would offer no benefit whatsoever. All prior standards in widespread use were abandoned during the 20th century in favour of defining the relevant units in terms of SI units. Specifically the international yard equals 0.9144 meters and the international pound equals 0.45359237 kilograms There literally isn't another definition, in the US when you say "100 yards" the only legal meaning that has is 91.44 metres, which is whatever CGPM / BIPM says it is.
