I know that lot of software is produced in USA but one would expect better from software developers.

I find it hard to believe that bold claim of “most”. The article doesn’t give evidence, not even a single example, so it doesn’t convince me I’m wrong in that.

If the output of a sensor that records in metric, then needs to be viewed in imperial it needs to be converted. Is it better to convert at write or read time always depends on use case and geography. Or do we just force the human in the loop to know that the speed limit is 112km/h even though it’s non digitally signposted at 70.

What's wrong with furlongs ? /s
