How to Convert Calories to Kilowatt-Hours
To convert a measurement in calories to a measurement in kilowatt-hours, multiply the energy by the following conversion ratio: 1.1622E-6 kilowatt-hours/calorie.
Since one calorie is equal to 1.1622E-6 kilowatt-hours, you can use this simple formula to convert:
kilowatt-hours = calories × 1.1622E-6
The energy in kilowatt-hours is equal to the energy in calories multiplied by 1.1622E-6.
Calories and kilowatt-hours are both units used to measure energy. Keep reading to learn more about each unit of measure.
What Is a Calorie?
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 Kilowatt-Hour?
A kilowatt-hour is a measure of electrical energy equal to one kilowatt, or 1,000 watts, of power over a one hour period. Kilowatt-hours are a measure of electrical work performed over a period of time, and are often used as a way of measuring energy usage by electric companies.
Kilowatt-hours are usually abbreviated as kWh, although the formally adopted expression is kW·h. The abbreviation kW h is also sometimes used. For example, 1 kilowatt-hour can be written as 1 kWh, 1 kW·h, or 1 kW 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.
