Not everybody is a mathematician or good with calculus that is why today we rely on the internet to provide us not only with calculations, but also with unit converters. These sites all function on the same principle. If you have a measurement you can either look it up or see how the system works. This enables you to convert the units yourself. Bit, if you are not sure or you have to convert units that are totally unknown to you (like some Asian ones or older units, that are no longer in use) you can simply type in the unit, type in the other unit and the unit converter will convert it by itself. This is a really easy and simple way to sort out all of your troubles.
