One caveat.
the current exposed by the bq27200 needs multiplied by (20/3.57)mA to get a current.

It's a raw value from the chip.
the '20' is arguable - but is at least more or less reasonable.
This is as the chip really reads out in units of 3.57uV, and the resistor the battery current is applied across is 20mR in the datasheet recommendation.
