...because it's a convenient fraction of a kilogramme which gives a bar of about the right size?

I hadn't thought of 62.5 being 1000/16.

It strikes me that 62.5 is exactly half way between the 2 more sensible sounding sizes of 50g and 75g. (This is hardly a full explanation, and in fact not why I guessed this number anyway!)

So it was once either 56.7g or 70.9g, and they found it either too big or too small and changed it.

They have tests about which size to make it, and people don't do round numbers.
