Energy Consumption Calculator

Energy Consumption Calculator

We are offering the Energy consumption calculator, to help you calculate the values of Energy Consumption in kWh.

Typical appliance:
Power consumption:
Hours of use per day: h/day
Energy consumed per day: kWh/day
Energy consumed per month: kWh/month
Energy consumed per year: kWh/year

Energy consumption calculation

The value of energy E in kilowatt-hours (kWh) per day is apparently equal to the value of power P in watts (W) multiplied by the number of usage hours per day t which is totally divided by the 1000 watts per kilowatt.

E(kWh/day) = P(W) × t(h/day) / 1000(W/kW)
