Background information

In the metric world you can go to a mechanic and ask for a iron rod, 5.32 cm (or 53.2 mm) long. If you would convert that to inch then you end up with 2.094488inch. Unfortunately nobody knows what that is. If you go to a workshop with that number then they don't know what to do. A mechanic's measurement tape in the imperial system has divisions of 1/16 inch or 1/32 inch (or 1/64 inch). In other words the mechanic wants full number of inches plus fractions and not inch with a decimal point. 5.32 cm is therefore equivalent to 2 3/32 inch.
