Electric energy or power consumption can be calculated using the following basic formula. Energy Consumption in Watt-hours = Power Rating in Wattage x Time in Hours

Free electricity calculator to estimate electricity usage as well as cost based on the power requirements and usage of appliances.

Electric consumption depends on only one thing: the power of a device. On a specification sheet, you will find power or wattage (expressed in Watts). The power consumption calculator above …

The energy E in kilowatt-hours (kWh) per day is equal to the power P in watts (W) times number of usage hours per day t divided by 1000 watts per kilowatt: E(kWh/day) = P(W) × t(h/day) / …

Hence, the energy consumption formula or the power consumption formula is given as below: E = P* (t/1000); where E = energy measured in Joules or kilowatt-hours (kWh), P = power units in …
