[units] coulombs to milliamp-hours
Hello, I am looking for a Coulombs to mAh (milliamp-hours) converter. It's conversion is a ratio I think: 1000 / 3600 (A -> mA, seconds -> hours). Haven't checked yet, but does SI include Coulombs? Or for that matter Amperes, where Coulomb = A s, I think. Thank ye. Regards, Michael Powell
Yes, to all your questions, so isn't 'conversion' just a simple calculation?

I suppose it is. I like the benefit of the code being readable, and if
units helps to check the safety at compile time, so much better.
Otherwise it's left to developer-discipline, which I can tell you on
the team I'm working with now, there's a lack of that.

Ah, yes, that... that's a much bigger problem. Maybe this isn't the issue on which to nail your colors to the mast. Presumably then, what you really need is a framework for ensuring dimensional integrity too? That's much more fun! - Rob.
In the sense I pick my battles, yes. I am operating as the architect
on the job, so the buck stops with me on that front. I get your point,
though, where cross-disciplinary boundaries go.
There's a difference though:
auto value = 10*coulombs;
auto mah_value = value*1000/3600;
What the unit for mah_value? Presumably the dimension is still
electrical_charge? But what is the unit? How to express that in the
units vocabulary?

Well, in complete ignorance of your environment, my general though is that you should keep to the base unit until the very last moment. Amps or milliamps is a matter for UI code, it's a presentation layer thing. - Rob.
