Detailed Description

Functions, constants, and classes for converting between different units.

In SpECTRE we prefer to use geometric units where $G=c=M_{\odot }=1$, as is standard in numerical relativity. However, in order to interface with other codes, we need to sometimes convert units. This namespace is designed to hold the various conversion factors and functions. A unit library/system would be nice, but is a non-trivial amount of work.
