Watts to kWh Conversion Calculator | Convert W to kWh

Watts to kWh Calculator & Convert W to kWh:

Enter watts: W
Enter power factor:  
   
Result in kilovolt-amps: kVA

Here Watt indicates the real power and kWh indicates the total energy consumption. We can get the total energy value by multiplying real power with the time period. To get the kilowatt-hour (kWh), we need to divide by 1000 for the above multiplications.

Let us assume,

E(kWh) = Energy Consumed by the circuit in kilo Watt-hour

P(W) = Real power supply to the circuit in Watts

t(hr) = Time in hours

By applying the above relation for converting watt (W) to Energy (kWh)

E(kWh) = P(W) * t(hr) / 1000

Example:

Let us assume an electric circuit takes 500 Watts per hour and the circuit used for 24 hours. Calculate the total energy consumed by the circuit in kWh – kilowatt-hour.

Use our formula,

E(kWh) = 500 * 24 / 1000

Total energy consumption E(kWh) = 12 kWh.
