au

Worth looking at: https://github.com/aurora-opensource/au It's a C++ library for handling physical quantities (and subsequent unit conversions)

I wanted to put in a plug for my employer's open-sourced C++ units framework, called Au: https://github.com/aurora-opensource/au The library incorporates dimensional units into the C++ type system with an emphasis on correctness (including considerations for overflow, rounding, loss of precision, etc) and minimal runtime overhead. As a very simple example of what using this library could look like, here is a tiny code snippet taken from one of the tutorials: constexpr double speed_mph = 65.0; constexpr double speed_mps = (miles / hour)(speed_mph).in(meters / second); In a larger program, of course, the whole point is to avoid using naked "doubles" (or floats or ints, etc) at all, and instead use the library's "Quantity" types, which encode information about their units. Conversions are done automatically, and incompatible operations

Aurora's C++ units library called "Au" (rhymes with "hey you!") has been a small but critical tool in Aurora's software development toolbox. Today, we're sharing it with the world[1]: Au is now open source for all to use. Feel free to ask me any questions! [1] https://blog.aurora.tech/engineering/introducing-au-our-open...
