How to convert calories to kilowatt-hours

Converting Calories (cal) to Kilowatt-hours (kWh) is a common task in energy measurements. Energy conversions connect food nutrition labels (calories), electricity bills (kWh), and scientific measurements in joules or BTU.

Formula: Multiply the calories value by 1.1622e-6. In equation form: kWh = cal × 1.1622e-6.

One calories equals approximately 0.000001 kWh. This means you can multiply any cal value by 0.000001 to get the equivalent in kWh.

For instance, converting 25 cal gives 0.000029 kWh. Try different values using the quick-value chips or type directly into the input field.

Common mistake: Food calories on nutrition labels are actually kilocalories (kcal), which confuses many people when comparing to joules or watt-hours.
