Please provide values below to convert Kilowatt-Hour [kWh] to Watt-Hour [Wh], or vice versa.
1 Kilowatt-Hour (kWh) = 1,000 Watt-Hour (Wh)
1 Watt-Hour (Wh) = 0.001 Kilowatt-Hour (kWh)
Example: convert 15 Kilowatt-Hour (kWh) to Watt-Hour (Wh):
15 Kilowatt-Hour (kWh) = 15 × 1,000 Watt-Hour (Wh) = 15,000 Watt-Hour (Wh)
A kilowatt-hour equals 3,600,000 joules. The standard unit for electricity billing.

|---|---|
| 1 kWh | 1,000 Wh |
| 2 kWh | 2,000 Wh |
| 5 kWh | 5,000 Wh |
| 10 kWh | 10,000 Wh |

Enter the input value, choose source and target units, and read the converted result shown instantly.
Converted Value = Input Value × (From Unit Factor / To Unit Factor). For non-linear domains, category-specific standard formulas are applied.
If 1 source unit equals 1000 target units, then 2 source units equal 2000 target units. Use the live converter above for exact values.
Q: Is this conversion accurate?
A: Yes, it uses fixed reference factors or tested standard formulas.
Q: Can I reverse the conversion?
A: Yes, swap the units or use the reverse conversion direction.
