cgs unit system

Hi, thank you for your awesome math library!

I am thinking about taking advantage of this library and build a calculator for physicists and astronomers. Since cgs unit system is still widely used in the astronomy community, I’d like to help to add a cgs unit system to this library.

I found UNIT_SYSTEMS.cgs but didn’t find a .toCGS() function. Here’s what I plan to do:

1. Complete UNIT_SYSTEMS.cgs: add a missing basic unit ‘Ba = g/(cm⋅s2)’; implement the ESU units system for Electromagnetics.
2. Define Unit.prototype.toCGS: copy Unit.prototype.toSI and change every instance of UNIT_SYSTEMS.si to UNIT_SYSTEMS.cgs.

Please let me know what do you think, or what is already in math.js that I missed.

Is there any other unit system other than SI, CGS, and US?

We can simply link .toSystem(‘SI’) to .toSI() and .toSystem(‘cgs’) to .toCGS(). The first step is to complete the CGS system. I’ll be working on that soon and make pull requests once finished.

Some day when I finish UnitMath

Still looking forward to that day 😎 👍
