Watts are a measurement of how many joules of work can be done in one second and are commonly used to indicate how much power an electrical device uses. Kilowatt hours are a measurement of energy and are used to calculate how much work can be done in an hour with one kilowatt--1,000 watts--of power.
A thousand watts is equal to 1 kilowatt (kW). Electric companies charge by the kilowatt hour (kWh), which is simply how many thousands of watts you use each hour. Starting with an object's wattage or kilowattage, you can calculate kilowatt hours using simple multiplication.
How to convert watts to kWh. How to convert electric power in watts (W) to energy in kilowatt-hour (kWh).. You can calculate kilowatt-hour from watts and hours. You can't convert watt to kilowatt-hour unit since watt and kilowatt-hour unit represent different quantities.
To convert the power in watts to kilowatt-hours, multiply 100 watts by 1 hour, then divide by 1,000 to find the energy usage in kWh. Energy = (100 × 1) ÷ 1,000 Energy = 100 ÷ 1,000 Energy = 0.1 kWh. If electricity costs $0.12 per kWh, then a 100 watt light bulb will cost 1.2 cents per hour that it’s on.
How to convert kWh to watts. How to convert energy in kilowatt-hour (kWh) to electric power in watts (W).. You can calculate watts from kilowatt-hour and hours. You can't convert kilowatt-hour to watt unit since kilowatt-hour and watt units represent different quantities.
How to Convert Kilowatt-Hours to Watts. A watt, expressed as W, is a measure of power while a kilowatt-hour is a measure of energy equivalent to 1,000 watt-hours, or 1,000 watts of power for 1 hour. So, to convert kilowatt-hours to watts, multiply the energy in kilowatt-hours by 1,000 to find the energy in watt-hours, then divide by the time in ...
To convert between watts to kilowatt-hours, first convert to kilowatts by dividing by 1,000, then multiply by the number of hours that the device is in use. For example, a 60-watt bulb that is on for five hours uses 0.06 kW per hour, for a total of 0.3 kWh.
Convert energy units. Easily convert kilowatt hours to watt hours, convert kWh to Wh . Many other converters available for free.
Electric companies charge by the kilowatt hour, which is a measure of electrical consumption over time. For example, if you ran a 100-Watt bulb for ten hours, you would use one kilowatt hour of electricity. In order to convert amps to kilowatt hours, you must also know the voltage and time.
Watts to kWh Calculator It is used to convert the electric power in watts (W) to energy in Kilowatt hours (kWh). The Kilowatt hour unit cannot be converted to watts directly because of the difference in their quantities. It is always important to fill in all the required text fields for the calculation to be successful.
