I have never thought of dollar as a physical unit. Namespace currency
perhaps.
const double pound = 1.0;
const double penny = pound / 100.0;
const double pence = penny;
const double euro = 1.0;
etc.

I have added UK English/European spellings. meter --> metre etc.

You have namespace metric, but these two might be useful.
const double metric_ton = ton;
const double metric_tons = ton;

What's wrong with using metric::ton or metric::tons?

Nothing at all. I was less sure about these two than the others,
hence my comment.
