Dividing by temperature

[deisner]

In some cases it is necessary to 'divide with temperatures'. For example, the SI unit for thermal conductivity is watts per meter-kelvin, i.e. W/(m*K). But I get an exception when I try to construct such a quantity:

> Qty(0.2, 'W m^-1 temp-K^-1')
Uncaught Error: Cannot divide with temperatures

Is there a way to represent such a quantity?
