Watts (W) to kilowatt-hours (kWh)

Calculator online find out the result

Watts (W) to kilowatt-hours (kWh)
The energy E in kilowatt-hours (kWh) is equal to the power P in watts (W), times the time period t in hours (hr) divided by 1000:

E_(kWh) = P_(W) x t_(hr) / 1000

Enter the power in watts, consumption time period in hours

watts		W
hours		hr
kilowatt hours		kWh

Power in watts (W) to energy in kilowatt-hours (kWh) calculator and calculation formula.

How to convert

WATTS: watt - the power consumed in the W unit of measurement

HOURS: hours - the time, expressed in hours, in which electricity consumption is achieved

KILOWATT HOURS: kWh - kilowatt hours. Energy consumed by the data entered in the table.

A kilowatt-hour, expressed as kWh or kW·h, is a measure of energy that is equivalent to 1,000 watts of power for a 1-hour time period.
Thus, to convert watts to kilowatt-hours, multiply the power in watts by the number of hours, then divide by 1,000.
