This is a good theory but the basic maths is that 1 mile = 1 km * 1.6 or vice versa. This is the basic thing you need to do.

However, this can get confusing it it get's to odd numbers etc, so what you can do is, simple leave it as miles because if you are in a miles country no one is converting it to km or vice versa.

Same with C and F in temperatures, there are basic maths systems that can do this in constant time, so there is no real reason to complicate it unless you want to do it in your head and then there is the basic maths to do it, if you can't just use a calculator.

My relatives & friends visiting from Europe often appreciate knowing such values in km/C. There are various other reasons to want to do the conversions too, and sometimes speed > accuracy. It's a bit ridiculous to think that _no one_ is doing these conversions and that shortcuts/approximations like this are not useful.

Maybe true in a miles country, I'm not sure.

However, so much stuff posted on the internet just assumes you are from the states, so they use imperial measurements only, and most of the rest of the world does need to do these conversions. I'm converting on an almost daily basis.

It's a minor peeve of mine that many people assume English means miles and pounds, when there are millions of tourists etc reading the English signs who want the original, metric measurements.
