1 kilojoule (kj) equals approximately 0.0002778 kilowatt-hours (kwh).
To convert 1 kj to kwh, you multiply the energy value in kj by 0.0002778 because 1 kj equals 0.0002778 kwh, based on the conversion factors between joules and watt-hours. This conversion helps relate energy measured in the metric system to electrical energy units used globally.
Conversion Result and Explanation
Converting 1 kj to kwh gives about 0.0002778 kwh. This tiny number shows how much electrical energy is equivalent to a small amount of chemical or mechanical energy measured in kilojoules. Understanding this helps compare energy sources and consumption more easily in different contexts.

Conversion Formula
The formula to convert kj to kwh is: kwh = kj * 0.0002778. This works because 1 joule equals 0.0002778 watt-hours, and since 1 kilojoule equals 1000 joules, multiplying kj by 0.0002778 gives the energy in kwh. For example, converting 10 kj:
- 10 kj × 0.0002778 = 0.002778 kwh
Conversion Example
- Convert 5 kj:
- Step 1: Take 5 kj.
- Step 2: Multiply 5 by 0.0002778.
- Step 3: 5 × 0.0002778 = 0.001389 kwh.
- Convert 20 kj:
- Step 1: Take 20 kj.
- Step 2: Multiply 20 by 0.0002778.
- Step 3: 20 × 0.0002778 = 0.005556 kwh.
- Convert 15 kj:
- Step 1: Take 15 kj.
- Step 2: Multiply 15 by 0.0002778.
- Step 3: 15 × 0.0002778 = 0.004167 kwh.
