library to manipulate units of physical quantities
The UDUNITS-2 provides support for units of physical quantities.

Its three main components are: 1) a C library for units of physical
quantities; 2) a utility for obtaining the definition of a unit and for
converting numeric values between compatible units; 3) an extensive
database of units.
