How do you calculate kW?

Method 2 Calculating Kilowatt Hours from Amps and Voltage
  1. Find the amps rating on your appliance. Some appliance labels do not list watts.
  2. Find the voltage in your region.
  3. Multiple amps and volts together.
  4. Multiply by hours used per day.
  5. Divide by 1000.
  6. Multiply to find the kilowatt hours for a larger time period.

How many amps is 1000w?

A 1000w HPS or Metal Halide light takes 9 amps at 120 volts so you can only run one on a wall outlet circuit. A standard dryer outlet is 220 volts and 30 amps so you can power up to six 1000 watt lights on that circuit.
