A map of which countries use imperial and which use the metric system around the world

In the UK we tend to measure our height in feet and inches, our beer in pints and our distances in kilometres.

This is of course a random mix of imperial and metric measurement, something Reddit user Tyler1492 has helpfully illustrated.

As you can see, there are very few countries highlighted in red - that's because the US is the only industrialised country in the world that hasn't officially adopted the metric system.

Which may go some way to explaining the description...
