Data for handling of units of physical quantities
The UDUNITS package supports units of physical quantities (e.g., meters, seconds). Specifically, it supports conversion between string and binary representations of units, arithmetic manipulation of units, and conversion of numeric values between compatible units. The package is written in the C programming language.
