Kilowatts (kW) to Kilowatt-hours (kWh) Calculator
Energy in kilowatt-hours:
Calculation Formula
E(kWh) = P(kW) × t(h)
Where:
- E(kWh) is the energy in kilowatt-hours
- P(kW) is the power in kilowatts
- t(h) is the time in hours
How to Convert kW to kWh
To convert from kilowatts (kW) to kilowatt-hours (kWh), you need to know:
- The power consumption in kilowatts (kW)
- The time period in hours (h) during which the power is consumed
The energy E in kilowatt-hours (kWh) is equal to the power P in kilowatts (kW), multiplied by the time period t in hours (h):
Example Calculations
Basic example
What is the energy consumption in kWh when the power consumption is 5 kW for time duration of 3 hours?
E = 5kW × 3h = 15kWh
Long duration example
What is the energy consumption in kWh when the power consumption is 1.5 kW for time duration of 24 hours?
E = 1.5kW × 24h = 36kWh
Fractional time example
What is the energy consumption in kWh when the power consumption is 2 kW for time duration of 0.5 hours?
E = 2kW × 0.5h = 1kWh
kW to kWh Conversion Table
| Power (kW) | Time (hours) | Energy (kWh) |
|---|---|---|
| 1 kW | 1 h | 1 kWh |
