How to Convert Kilocalories to Watt-Hours

To convert a measurement in kilocalories to a measurement in watt-hours, multiply the energy by the following conversion ratio: 1.162222 watt-hours/kilocalorie.

Since one kilocalorie is equal to 1.162222 watt-hours, you can use this simple formula to convert:

watt-hours = kilocalories × 1.162222

The energy in watt-hours is equal to the energy in kilocalories multiplied by 1.162222.

For example, here's how to convert 5 kilocalories to watt-hours using the formula above.

watt-hours = (5 kcal × 1.162222) = 5.811111 Wh

How Many Watt-Hours Are in a Kilocalorie?

There are 1.162222 watt-hours in a kilocalorie, which is why we use this value in the formula above.

1 kcal = 1.162222 Wh

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

What Is a Kilocalorie?

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.

What Is a Watt-Hour?

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

Watt-hours are usually abbreviated as Wh, although the formally adopted expression is W·h. The abbreviation W h is also sometimes used. For example, 1 watt-hour can be written as 1 Wh, 1 W·h, or 1 W h.

In formal expressions, the centered dot (·) or space is used to separate units used to indicate multiplication in an expression and to avoid conflicting prefixes being misinterpreted as a unit symbol.[1]
