How to Convert Kilowatt-Hours (kWh) to Watts (W)

To convert Kilowatt-hours (kWh) to Watts (W), use the formula:

The power P in watts (W) is equal to the energy E in kilowatt-hours (kWh) divided by the time t in hours (h) and then multiplied by 1,000:

P(W) = (E(kWh) / t(h)) × 1,000

If you have an energy measurement of 5 kWh and the time is 2 hours, the calculation would be:

P(W) = (5 kWh / 2 h) × 1,000 = 2,500 W

Kilowatt-hours (kWh) represent the total energy consumed or produced over time. For more information, visit this resource.

Time in hours represents the duration of energy consumption. It’s essential for calculating power output.

Watts (W) measure the rate of energy transfer or conversion, indicating how much energy is used per unit of time.

Formula: W = (kWh × 1000) / Time (in hours)

Kilowatt-hours [kWh]	Watts at 1 hour	Watts at 2 hours	Watts at 3 hours	Watts at 4 hours
1 kWh	1000 W	500 W	333.33 W	250 W
2 kWh	2000 W	1000 W	666.67 W	500 W
3 kWh	3000 W	1500 W	1000 W	750 W
4 kWh	4000 W	2000 W	1333.33 W	1000 W
5 kWh	5000 W	2500 W	1666.67 W	1250 W
10 kWh	10000 W	5000 W	3333.33 W	2500 W
20 kWh	20000 W	10000 W	6666.67 W	5000 W
