Improving our safety with a physical quantities and units library

1. Squants

   1 8 930 1.6 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 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;

   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:
