## What it is
Pint is a Python library for defining, operating on, and manipulating physical quantities (a numerical value paired with a unit of measurement). It supports arithmetic between quantities, unit conversions, a comprehensive built-in set of units and constants, and numpy integration.

## Use cases
- convert between units of measurement in Python
- do arithmetic on quantities with units like meters and seconds
- avoid unit conversion bugs in scientific code
- work with numpy arrays that carry physical units
- build a unit converter CLI
- define custom units and constants for a domain

## When to choose
- your Python code mixes quantities with different units and needs safe conversions
- you want numpy-compatible physical quantities with minimal dependencies
- you need an extensible units registry with custom units, prefixes, and constants

## When to avoid
- you need symbolic math or a full computer algebra system
- your project is not in Python
- you only need a one-off unit conversion without a library dependency

## Facets
- artifact type: library
- maturity: stable
- function: math, serialization
- domain: data-science, developer-tools
- platform: python, cross-platform
- tags: units-of-measurement, physical-quantities, unit-conversion, numpy, scientific-computing, science
