To convert watts to amps, you need to know the voltage at which the power is being used.
Conversion Formula for watts to amps
Amps (A) = Watts (W) / Volts (V)
In this case, you have 100 watts, but you haven’t mentioned the voltage. Without knowing the voltage, you cannot convert watts to amps. Watts and amps are related to each other through voltage, so you need to have the voltage value to make the conversion.
Once you know the voltage, simply divide the number of watts by the voltage in volts to find the amperage.
Solved Example
if you are working with a standard 120-volt electrical system:
Amps (A) = 100 watts / 120 volts
Amps (A) = 0.8333 amps (rounded to the nearest thousandth)
So, if you have 100 watts at 120 volts, it would be approximately 0.8333 amps.
