How to Convert Kilocalories to Kilojoules
To convert a kilocalorie measurement to a kilojoule measurement, multiply the energy by the conversion ratio. One kilocalorie is equal to 4.184 kilojoules, so use this simple formula to convert:
The energy in kilojoules is equal to the kilocalories multiplied by 4.184.
Kilocalories and kilojoules 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.
Kilojoules
One kilojoule is equal to 1,000 joules, which are the energy equal to the force on an object of one newton at a distance of one meter.
The kilojoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "kilo" is the prefix for 103. Kilojoules can be abbreviated as kJ; for example, 1 kilojoule can be written as 1 kJ.
