People do not like change, in that sense people are conservative. Americans would benefit from going over to SI, but many don't want to change.
@tadbithuman America is metric, it just doesn't realise it.
@tadbithuman No. It really is. Under the hood, for all the anti metric sentiment, an inch is defined as 25.4mm
It is grand that the survey foot was retired at the end of 2022.
@tadbithuman Exactly. US is a metric country, it just doesn't want to admit it.
@quixoticgeek ah yes, in fact all geodetic surveys in America are performed in metres and then converted to the standard foot (0.3048 m) and/or US survey foot (0.3048006096 m).
The two different measures of feet cause problems when not handled carefully with long things like highways.
