I’m originally from the US. Since living in Europe, I can’t believe how much easier the metric system is. I can not convert between the two so I dropped imperial. The only time I deal with it is when I call family in the states.
I do recall, when I was a kid, they tried to convert the US to metric, but it failed miserably.
I’ll wait for a FOSS app. Redreader supposedly will support Lemmy in the future.
