I have often wondered why the USA does not use
- the metric system
- ISO paper sizes
Is it because the US is so big that it is quite possible to use a system not used in the rest of the world, because you can get by using just what you know?
It must be difficult when travelling abroad or buying things online if the systems of measurement are not the same as what you know. I know how hard it was the first time I had to drive on the right-hand side of the road!
South Africa transitioned from the imperial system to the metric system during the years I was at school, before switching totally over to metric. This means that I can do conversions in my head from stones to kg, ounces to grams, square feet to square metres, yards to metres etc. I never thought I would appreciate that but it means I can figure out the size and weight of things when buying online or reading foreign books, for example.
