Conversions are easily done with AddUp. All you need to know is units you want to convert from, the unit you want to convert to, and the fact that the -> conversion operator is there for you. Convert one unit into another by typing a number and its unit, followed by the conversion operator, followed by the unit you wish to convert into. Alternatively, you can use the "convert" function to get the same result. The following table shows only a few possible examples, there are many more. Refer to the Units and Conversions section of the reference for details.
