Kilowatts to Kilowatt-Hour Converter
How to Convert Kilowatts (kW) to Kilowatt Hours (kWh)
To convert Kilowatts (kW) to Kilowatt-hours (kWh), use the formula:
kW to kWh Calculation Formula
The energy E in kilowatt hours (kWh) is equal to the power P in kilowatts (kW) multiplied by the time t in hours (h):
E(kWh) = P(kW) × t(h)Example Calculation
If you have a power measurement of 2 kW and the time is 3 hours, the calculation would be:
E(kWh) = 2 kW × 3 h = 6 kWhUnderstanding the Conversion
Power (kW)
Kilowatts (kW) are the standard SI unit of power, measuring the rate at which energy is transferred or work is done. One watt is defined as one joule of energy per second. Learn more about watts and power measurements.
Time (h)
Time in hours represents the duration of power consumption or generation. It’s essential for calculating total energy usage as energy is the product of power and time.
Energy (kWh)
Kilowatt hours (kWh) measure electrical energy consumption. One kWh equals the energy transferred when 1,000 watts of power is sustained for one hour, commonly used in electrical utility billing.
