FAQ for kJ → kWh

Formula?

kWh = kJ × 0.000278 (1 KJ = 0.000278 KWH)

Reverse?

1 kilowatt-hour ≈ 3600 kilojoule.

How much is 1 kilojoule in kilowatt-hour?

0.000278 kilowatt-hour. Factor 1 kilojoule = 0.000278 kilowatt-hour.

Is kWh the same as a food calorie?

No. kWh is electrical energy; kcal is common on food labels. We only convert physical energy equivalents.

How many kcal in 1 kWh?

About 860.4 kcal (thermochemical, since 1 kWh = 3.6 MJ). See the live factor on this page.

How the Kilojoule to Kilowatt-hour converter works

This hub describes the pair, not a single number. Pages like 1, 10 or 100 Kilojoule answer exact searches.

NiftyRecipe uses thermochemical energy factors (for example 1 kcal = 4184 J). Results do not change with the time of day.
