This is a pure Lua library which provides functions and object for doing computation with physical quantities.
In general, a physical quantity consists of a numerical value called magnitude and a unit. There are restrictions to the allowed mathematical operations with physical quantities. For example the quantity time cannot be added to the quantity mass. Furthermore, new quantities can be obtained by multiplication or division from other base quantities. The density is such an example. It can be calculated by dividing the mass of a body by its volume.
