How to Convert Calories to Watt-Hours
Joe is the creator of Inch Calculator and has over 20 years of experience in engineering and construction. He holds several degrees and certifications.
To convert a measurement in calories to a measurement in watt-hours, multiply the energy by the following conversion ratio: 0.001162 watt-hours/calorie.
Since one calorie is equal to 0.001162 watt-hours, you can use this simple formula to convert:
watt-hours = calories × 0.001162
The energy in watt-hours is equal to the energy in calories multiplied by 0.001162.
Calories and watt-hours are both units used to measure energy. Keep reading to learn more about each unit of measure.
What Is a Calorie?
One calorie is equal to the heat needed to raise the temperature of one gram of water from 14.5 to 15.5 degrees Celsius.
When measuring the energy content in foods, the large calorie, or kilocalorie is used, but it's often still just called a "calorie." When both the calorie and large calorie are used in the same context it is common to refer to the calorie as a "small calorie."
Calories can be abbreviated as cal; for example, 1 calorie can be written as 1 cal.

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]
