Someone please explain what a cubic second is! Often such cancellation produces a unit that is hard to understand. For instance, all resistivities include the term square meter per meter, which cancels to meter. A tog per decimeter, which is easy to understand, turns into a kelvin meter per watt, and it's not obvious what the meter is doing there. Likewise electrical resistivity is measured in ohm meters, which are really ohm square meters per meter. phma
