Kilocalories to Watt-hours Conversion
Enter the energy in kilocalories below to get the value converted to watt-hours.
How to Convert Kilocalories to Watt-hours
To convert a kilocalorie measurement to a watt-hour measurement, multiply the energy by the conversion ratio. One kilocalorie is equal to 1.162222 watt-hours, so use this simple formula to convert:
The energy in watt-hours is equal to the kilocalories multiplied by 1.162222.
Kilocalories and watt-hours are both units used to measure energy. Keep reading to learn more about each unit of measure.
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.
Watt-hours
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]
