Kilowatts to kilowatt-hours calculator

Enter power in kilowatts: kW
Enter time in hours: h
Energy result in kilowatt-hours: kWh

Have you at any point considered how your electric bill is determined? You realize that you are utilizing 60-watt bulbs all through your home, for instance, yet you might not have known that in the event that one of those bulbs is turned on for five hours per day, it utilizes 10.8 kilowatt hours out of every month- - at an expense of about $1.30 per bulb, in light of the public normal. Duplicate that by every one of the bulbs in your home and you start to perceive how your power bill can add up. Power can be estimated in wattage, or the rate at which power is utilized at a given second. 1,000 watts is equivalent to 1 kilowatt (kW). Electric organizations charge by the kilowatt hour (kWh), which is essentially the number of thousands of watts you that utilization every hour. Beginning with an item's wattage or kilowattage, you can work out kilowatt hours utilizing basic multiplication.

Calculating kilowatt hours

Find out the number of watts a gadget that utilizes each hour. Look on the mark or in the guidance manual, or use Mr. Power's intelligent graph at (see Assets for connect). A 60W light clearly utilizes 60 watts each hour. A typical PC utilizes around 45 watts for each hour.

Kilowatts to kilowatt-hour estimation formula

The energy E in kilowatt-hour (kWh) is equivalent to the power P in kilowatts (kW), times the time span t in hours (hr):

E(kWh) = P(kW) × t(hr)


kilowatt-hour = kilowatt × hour


kWh = kW × hr


What is the energy utilization in watt-hour when the power utilization is 5 kilowatts for time length of 3 hours?

E = 5kW × 3h = 15 kWh
