It is not unusual for one to desire a unit-conversion constant when the developer understands
[*] FPU isn't available
[*] Can be done quickly without a framework
[*] Using a framework to normalize to a base unit, apply a translation, and return the desired reuslt is considered overkill
These functions are not to be converted into such a convoluted templated potentially-constexpr castable mess
The intention is to keep these utility functions as simple as the dumb operations they implement
