## What it is
Units.NET is a .NET library providing strongly typed quantities and units of measurement with unit conversion, parsing, and localization support. It eliminates magic constants by letting code work with typed quantities like Length and Mass across hundreds of units.

## Use cases
- convert between units of measurement in C#
- parse unit strings like '5 m/s' into typed quantities
- avoid magic constants for units in .NET code
- build a unit converter app
- serialize quantities to JSON or XML
- localize unit abbreviations by culture

## When to choose
- you write .NET/C# code dealing with physical quantities or measurements
- you need strongly typed units with operator overloads and culture-aware parsing
- you want a mature, widely used MIT-licensed library on NuGet

## When to avoid
- your project is not on .NET (though sibling ports exist for other platforms)
- you only need one-off conversions a simple formula can handle
- you need a modular build with only a few units and can't use the experimental UnitsNet.Modular

## Facets
- artifact type: library
