Kilocalories to Joules Conversion
Enter the energy in kilocalories below to get the value converted to joules.
How to Convert Kilocalories to Joules
To convert a kilocalorie measurement to a joule measurement, multiply the energy by the conversion ratio. One kilocalorie is equal to 4,184 joules, so use this simple formula to convert:
The energy in joules is equal to the kilocalories multiplied by 4,184.
Kilocalories and joules 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.
Joules
The joule is the energy equal to the force on an object of one newton at a distance of one meter.[1] One joule is equal to the heat energy dissipated by the current of one ampere through one ohm of resistance for one second.
One joule is also equal to the energy needed to move an electric charge of one coulomb through a potential difference of one volt. In addition, one joule is also equal to the one watt-second.
The joule is the SI derived unit for energy in the metric system. Joules can be abbreviated as J, for example 1 joule can be written as 1 J.
