Use and manipulate unit-aware measurement objects in Python

Easily use and manipulate unit-aware measurement objects in Python.

django.contrib.gis.measure has these wonderful 'Distance' objects that can be used not only for storing a unit-aware distance measurement, but also for converting between different units and adding/subtracting these objects from one another.

This module not only provides those Distance and Area measurement objects, but also other measurements including:

  • Energy
  • Speed
  • Temperature
  • Time
  • Volume
  • Weight

Example:

>>> from measurement.measures import Weight
>>> weight_1 = Weight(lb=125)
>>> weight_2 = Weight(kg=40)
>>> added_together = weight_1 + weight_2
>>> added_together
Weight(lb=213.184976807)
>>> added_together.kg  # Maybe I actually need this value in kg?
96.699

Warning

Measurements are stored internally by converting them to a floating-point number of a (generally) reasonable SI unit. Given that floating-point numbers are very slightly lossy, you should be aware of any inaccuracies that this might cause.

TLDR: Do not use this in navigation algorithms guiding probes into the atmosphere of extraterrestrial worlds.
