Improving our safety with a physical quantities and units library

• Squants

  8 910 2.9 Scala

  The Scala API for Quantities, Units of Measure and Dimensional Analysis

  

Scala's squants library is a nice implementation of units-of-measure/dimensional-analysis http://www.squants.com

In particular it uses types for dimensions; whilst units are just constructors. Hence `Meters(2)` and `Microns(7)` have the same type (`Length`).

• manifold

  79 2,238 9.3 Java

  Manifold is a Java compiler plugin, its features include Metaprogramming, Properties, Extension Methods, Operator Overloading, Templates, a Preprocessor, and more.

  

The manifold[1] project for Java lets you write unit expressions directly.

Force force = 5kg * 9.807 m/s/s;

• unit-syntax

  1 5 8.0 Python

For folks interested in this kind of thing, I wrote a python package called [unit-syntax](https://github.com/ahupp/unit-syntax) that adds physical unit syntax to python:
