# Units

Experimenting with runtime unit systems in python, and benchmarking a few popular ones.

To fully build this you'll need rust installed.

Here's the output of running the `try_all.py` script, which runs some timings for simple operations.

The main point is that the `ostrich` library (a massively incomplete system prototyped within this repo) is basically the lowest overhead option that is possible in CPython:

```

moooo> make

moooo> uv run python units/try_all.py

Unyt:

Scalar overhead: 284.74

Array overhead:  19.93

Astropy:

Scalar overhead: 514.04

Array overhead:  27.25

Pint:

Scalar overhead: 326.73

Array overhead:  28.26

Ostrich:

Scalar overhead: 5.40

Array overhead:  1.68

```
