Good point - I don't think there's a precision issue, but I should
think about
it some more. I'll take a look at this later this evening. I guess it
can be rendered down
even more:
static
quantity<unit<System2,Dim1>,Y>
convert(const quantity<unit<System1,Dim1>,Y>& source)
{
static Y fac(compute_factor());
return quantity<unit<System2,Dim1>,Y>::from_value
(source.value()*fac);
}
