Kilowatt hour calculator
For example lets calculate the power consumed by a 10 watt bulb if it runs for 24 hours in a day for the entire month. Energy use in kilowatt-hours is determined by multiplying the number of hours appliance operates by its rated power in kilowatts.

Formula of converting watts to Kilowatt hours E kWh P W x t hr 1000 which means that the energy.
. Amp Hours 12V. PkW PF IA VV 1000 AC three phase amps to kilowatts calculation Calculation with line to line voltage The power P in kilowatts kW is equal to square root of 3 times the power factor. 500 watts x 2 hours 1000.
Divide the watt hours by 1000 to calculate the kilowatt hour. Start by converting the number of watts that your appliance uses to kilowatts. You dont have to find a calculator and figure out what types of numbers to plug in because our calculator asks you for the data.
EkWh PW thr 1000 Watts to kWh calculation See also. We then multiply the electricity cost per kilowatt hour to. BTUh is often abbreviated to just BTU to.
Kilowatt-hours kWh is the electricity demand for an appliance to run. Here is a conversion chart converting common kilowatt hour values to amp hours at 12V and 24V. This calculator uses the average watt rating 100 Watts for a Refrigerator.
Perhaps you have a 500-watt drill. Heres how you calculate the number of kilowatt-hours of electricity you use. Divide the wattage amount by 1000.
Kilowatts kW is equivalent to 1000 watts. Enter the price per. Benefits of our Kilowatt Hour Cost Calculator include.
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. To calculate watts from. Energy consumption calculation The energy E in kilowatt-hours kWh per day is equal to the power P in watts W times number of usage.
To run it on low takes 500 watts of power. 3-Phase Power Formula Heres the simple formula we use to calculate power on a 1-phase AC circuit. EkWh 2kW 3h 6kWh kWh to Wh MWh BTU kBTU J kJ MJ GJ conversion 1kWh 1000Wh 0001MWh 1kWh 341214163312794 BTU IT 341214163312794 kBTU IT 1kWh.
So in order to convert kilowatt hours to watts you must know how many hours it took to generate or use the measured amount of kilowatt hours. To calculate kilowatt hours simply multiply the amp hours times voltage then. 1 BTU 00002931 kWh 1 kWh 3412 BTU BTUh BTU per hour is a unit of power that represents the energy transfer rate of BTU per hour.
E kWh P kW x t hr which means that the energy in Kilowatt-hours is calculated by multiplying the power in Kilowatts by the time in hours. It is commonly displayed on the platform under the Calculate and Reset controls. The specifications for any battery will indicate a rating for both volts as well as amp hours.
Amp Hours 24V. It will take two hours of cumulative usage over time to consume one kWh of energy. Watt is the standard unit of electrical power.
P kW I Amps V Volts 1000 Basically we just multiply amp by volts. You can input your Refrigerators details to calculate the exact usage and cost of your device. For example If the power in kilowatts is.
