JFC I though America had it fucked up sideways

We’d need several versions of this in the UK with a decision tree required to select the relevant decision tree. It would need to take age and where you were brought up into account.

I think that the most complicated is distance. For me it is imperial for a person’s height, metric for short distances that I measure, imperial for short distances that I estimate (that one’s weird), miles for ground travel distances and time for air travel distances.

Thank you, I’m tired of people saying only the US still uses imperial units.

UK, Ireland, Canada, Australia, … and more still use them.

And the whole aviation industry is using feet for altitude and the whole world is using inches for screen sizes.
