- Ensures dimensional consistency in calculations, helps prevent unit errors, highly flexible and extensible, good integration with NumPy, excellent documentation, actively maintained.
- Can add a slight performance overhead compared to raw numerical calculations (though often negligible), can be verbose if units need to be attached to every number explicitly, requires careful definition of custom units or contexts.
最适合：
- Scientists, engineers, and developers who need to perform calculations involving physical quantities with units, ensuring correctness and preventing common unit-related errors.
