How to Convert Kilowatts to Kilowatt-Hours
Kilowatts, or kW, are a measure of electrical power. Kilowatt-hours, abbreviated as kWh or kW·h, are a measure of energy used. One kilowatt-hour is equal to one kilowatt of power consumed over a one-hour time period.
kW to kWh Conversion Formula
To convert power in kW to energy in kWh, use the formula below.
E(kWh) = P(kW) × T(hrs)
The energy E in kilowatt-hours is equal to the power P consumed in kilowatts times the time T in hours.
For example, let’s convert 25 kW power used over a 4-hour time period to energy in kWh.
EkWh = 25 kW × 4 hours
EkWh = 100 kWh
So, 25 kW of power consumed over 4 hours is equal to 100 kWh of energy.
