Non-linear unit conversion (Watts, dBW, dBm)

[jacob031]

Basically, I need to implement support for Watts to dBW and dBm. The conversion from Watts to dBW is defined as P(dBW) = 10*log10( P(w) / 1W ). Implementing this conversion using the options provided with the mathjs.createUnit function just doesn't seem possible.

I've had no luck in finding an alternative solution by searching various forums, the discussions here on Github, and the documentation. I feel like I am missing something obvious.

Any advice?

Ah, yeah, I think it's not possible right now to define non-linear unit conversions.

As a workaround you could maybe implement a helper function like wattToDBW(...).

@ericman314 do you have any thoughts in this regard?
