Real men us real math. :-) E=volts, I=amps, R=ohms, P=watts

Ohm's Law says that 1 volt will push 1 amp through 1 ohm, or another way, 1 volt is required to push 1 amp through 1 ohm.

E=IxR, I=E/R, R=E/I

If you increase the voltage or decrease the resistance, the current increases, and vice versa.

Watt's Law says that 1 amp at 1 volt produces 1 watt, or another way, 1 watt is dissipated by 1 amp pushed by 1 volt.

P=ExI, E=P/I, I=P/E

If you increase the voltage or increase the current, the power increases.

To use any of the above formulae, place the unknown value to the left.

Now, back to the original question. The formula to convert amps to watts is to multiply amps by 120. P=ExI= 120 x 15 = 1800 watts.
