## How do you calculate power consumption?

How to Calculate Power Consumption in kWh?

1. Daily Power Consumption. Daily Power Consumption = Wattage rating x time in hours. 2000 Watts x 3 Hrs = 6000 Watts-Hour.
2. Monthly Power Consumption. Monthly Power Consumption = Wattage rating x time in hours. 2000 Watts x 3 Hrs x 30 days = 180000 Watts-Hour.
3. Annual Power Consumption.
