Description:
converts between different systems of units
GNU 'units' program converts quantities expressed in various scales to their equivalents in other scales. The 'units' program can only handle multiplicative scale changes directly. It uses a functional notation for non-proportional conversions such a Fahrenheit temperature to Celsius temperature. . This package includes the units_cur script to update currency conversion information; this script requires a Python 3 interpreter and the python3-requests library.
