How to Convert Kilojoules to Watt-hours

Convert kilojoules to watt-hours with this simple formula:

watt-hours = kilojoules × 0.277778

Converting a kilojoule energy measurement to a watt-hour measurement involves multiplying the energy by the conversion ratio to find the result. One kilojoule is equal to 0.277778 watt-hours, so to convert simply multiply by 0.277778.

For example:
5 kJ = (5 × 0.277778) = 1.388889 Wh
