Convert watts to kilowatt-hours (kWh) given power in watts and time in hours. Learn how to calculate kilowatt-hours using a simple formula.
With this watts to kilowatt-hour chart, you can easily figure out how many kWh does a device with certain wattage and running for a certain amount of hours consume. You can use both the calculator and the chart.
Here is a conversion chart converting common values of watts to kilowatt hours, over a duration of one hour and one day. Converting watts to kilowatt hours is easy. First, multiply watts times hours, then divide by 1000. Formula: kilowatt hours = (watts × hours) ÷ 1000. Abbreviated: kWh = (W × hrs) ÷ 1000.
The Watts to kWh Calculator is a tool used to convert electrical power consumption from watts into kilowatt-hours. It is absolutely necessary to perform the conversion, which leads to the calculation of energy use for an appliance or any device that consumes electricity over a certain period of time.
Convert kWh given energy in kWh and time in hours, plus learn how to calculate watts from kilowatt-hours using an easy formula.
One of the most common units of electrical power for appliances is the watt (W). Other common units of power include kilowatts (kW), British thermal units (BTU), horsepower (hp), and tons. Watts, kilowatts and kilowatt-hours: Watts (W) is a unit of power used to quantify the rate of energy transfer. It is defined as 1 joule per second.
Enter electric appliance in the dropdown menu or enter manual wattage rating in watts or kilowatts (kW) and the daily usage of the device in hours. Click the calculate button to determine the daily, monthly and annual power usage or energy consumption in kWh.
The formula to convert watts to kilowatt-hours is: kWh = W/1000. This formula shows that 1 kWh is equal to 1000 watts used for one hour. Table of Watts to kWh Conversions. Below is a table showing the conversion of various watt values to kilowatt-hours, sorted from smallest to largest.
For example: let’s find the kWh of 3000 watts for 2 hours. E (kWh) = 3000 × 2 / 1000 = 6 kWh. Sure, here’s a table showing the conversion of power in watts to kilowatt hours (kWh) for a period of one hour, from 100 watts to 5000 watts: Automation Engineer. Electrical Engineer. Work experience: 22 years. Author of scientific publications.
Watts to kWh calculator 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.
