A kilowatt-hour, communicated as kWh or kW·h, is a proportion of energy that is identical to 1,000 watts of force for a 1-hour time span. In this way, to switch watts over completely to kilowatt-hours, duplicate the power in watts by the quantity of hours, then partition by 1,000.

Use the accompanying equation to work out kWh:

E_(kWh) = P_(W) × t_(hr)/1000

Power use is determined in kilowatt-hours. A kilowatt-hour is 1,000 watts utilized for one hour.Here's the Recipe for Working out Watts Into Kilowatt-Hours: kWh = (watts × hrs) ÷ 1,000.Simply put, a kilowatt is the estimation of force while a kilowatt hour (kWh) is the period of time something can utilize a kW. One kilowatt hour is equivalent to 1,000 watts supported for one hour.To work out the kWh for a particular machine, increase the power rating (watts) of the machine by how much time (hrs) you utilize the apparatus and separation by 1000.
