unyt 3.1.0

A package for handling numpy arrays with units

A package for handling numpy arrays with units.

Often writing code that deals with data that has units can be confusing. A function might return an array but at least with plain NumPy arrays, there is no way to easily tell what the units of the data are without somehow knowing a priori.

The unyt package (pronounced like “unit”) provides a subclass of NumPy’s ndarray class that knows about units. For example, one could do:

>>> import unyt as u
>>> distance_traveled = [3.4, 5.8, 7.2] * u.mile
>>> print(distance_traveled.to('km'))
[ 5.4717696  9.3341952 11.5872768] km

And a whole lot more! See the documentation for installation instructions, more examples, and full API reference.

This package only depends on numpy and sympy. Notably, it does not depend on yt and it is written in pure Python.
