In the Natural Units environment, the diff function differentiates an expression with respect to a name that can have a unit.  The result is the derivative of the expression, with respect to the variable of differentiation, with a unit, the input expression unit divided by the variable of differentiation unit if any.

For other properties, see the global function diff.
