Watts law, Power in Watts is equal to the inductive resistance in amps times the voltage.
That is a bit muddled:

1. "inductive resistance". There is "inductive reactance" (which dissipates no real power) and yes practical inductors do have non-zero resistance but "inductive resistance" is not a recognised term.

2. "resistance in amps" is incorrect. The unit of resistance is Ohm. Amps (short for Ampere) is the unit of current.
The unit of resistance is "ohm". The unit of current is "ampere" (often shortened to "amp").
Ohm and Ampere (Amp) is the convention I've always understood. Where a unit is named after a person then the first letter is capitalised.

Hence kWh, mA, kV etc.
