Watts to KWh Calculator


The Watts to Kilowatt Hours Calculator converts electric power in watts (W) to energy in Kilowatt hours (kWh).

The formula for converting Watts to Kilowatt hours is as follows:

E = P x t / 1000

Thus, the energy in Kilowatt hours is calculated by multiplying the power in watts by the time in seconds and then dividing the result by 1000.
