The qunits Python package provides a performant, verbose and generic physical unit system. Tutorials and the API documentation are available on the Homepage. Additional example scripts can be found in the example folder on GitHub.

Getting started

from qunits import u

q = 2 * u.e  # >>> 2.0 e
v = 2e5 * u.m / u.s  # >>> 200000.0 m/s
B = 0.42 * u.mT  # >>> 0.42 mT

F = q * v * B  # >>> 168000.0 e⋅m⋅mT/s
F = F.to_base_units()  # >>> 2.6916567451199998e-17 N
F = F.to(u.e * u.V / u.m)  # >>> 168.0 e⋅V/m
