QUICK REFERENCE TO UNITS
Many older people have grown up having to study with up to three different types of units until the ISO units were accepted.
However, some generations do not like to admit that they still have problems working with ISO units, especially if they only have to use them infrequently. The unit system that they learnt at scool and college has remained with them and they still tend work in the older units they more comfortable with and then convert to the ISO units when they have the answer.
So for the over 40's, We hope this quick check list will help you. Who knows, it may also prove of benefit to younger peolpe as well.
