Convert Kilocalories to Kilowatt-hours

Whether you need to express a value in kWh instead of kcal, this guide walks you through the exact steps. Energy conversions connect food nutrition labels (calories), electricity bills (kWh), and scientific measurements in joules or BTU.

To convert, multiply the kilocalories value by 0.00116222. Written as an equation: kWh = kcal × 0.00116222.

One kilocalories equals approximately 0.001162 kWh. This means you can multiply any kcal value by 0.001162 to get the equivalent in kWh.

Worked example: 5 kcal = 0.005811 kWh. Enter your own value in the converter above for instant results.
