How to Convert Watt-hours to Kilocalories

To convert a watt-hour measurement to a kilocalorie measurement, multiply the energy by the conversion ratio. One watt-hour is equal to 0.860421 kilocalories, so use this simple formula to convert:

kilocalories = watt-hours × 0.860421

The energy in kilocalories is equal to the watt-hours multiplied by 0.860421.

For example, here's how to convert 5 watt-hours to kilocalories using the formula above.
5 Wh = (5 × 0.860421) = 4.302103 kcal

Watt-hours and kilocalories are both units used to measure energy. Keep reading to learn more about each unit of measure.

Watt-hours

The watt-hour is a measure of electrical energy equal to one watt of power over a one hour period.

Watt-hours can be abbreviated as Wh, for example 1 watt-hour can be written as 1 Wh.

Kilocalories

One kilocalorie, is equal to the heat needed to raise the temperature of one kilogram of water from 14.5 to 15.5 degrees Celsius.

Kilocalories can be abbreviated as kcal, for example 1 kilocalorie can be written as 1 kcal.

When being used to measure nutrition or metabolic processes, the large calorie is used, which is equal to one kilocalorie.
