GCB CI status:

Implements unit of measurement arithmetic, where a number is associated with a product of powers of base units and values with compatible units can be added.

Defines SI units, SI prefixes, and some derived units.

Example

import tunits
from tunits.units import meter, km, N

print(5*meter + km)
# 1005.0 meter

print(N/meter)
# N/meter

print((N/meter).inBaseUnits())
# kg/s^2

print(2*km / tunits.Value(3, 's'))
# 0.666666666667 km/s
