Kilojoules to Kilocalories

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.

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.

How to convert from kilojoules to kcal

Kilojoules to thermochemical / food kilocalories

1 kcalth = 4.184 kJ

The energy in kilocalories E(kcal-th) is equal to the energy in kilojoules E(kJ) divided by 4.184:

E(kcal) = E(kJ) / 4.184

Example

Convert 5 kilojoules to kilocalories.

E(kcal) = 5 kJ / 4.184 = 1.195 kcal

Kilojoules to international kilocalories

1 kcalIT = 4.1868 kJ

The energy in international kilocalories E(kcal-IT) is equal to the energy in kilojoules E(kJ) divided by 4.1868:

E(kcal-IT) = E(kJ) / 4.1868

Example

Convert 5 kilojoules to kilocalories.

E(kcal-IT) = 5 kJ / 4.1868 = 1.194 kcalIT

Kilojoules to 15°C kilocalories

1 kcal15 = 4.1855 kJ

The energy in 15°C kilocalories E(kcal15) is equal to the energy in kilojoules E(kJ) divided by 4.1855:

E(kcal15) = E(kJ) / 4.1855

Example

Convert 5 kilojoules to kilocalories.

E(kcal15) = 5 kJ / 4.1855 = 1.195 kcal15

Kilojoules to 20°C kilocalories

1 kcal20 = 4.182 kJ

The energy in 20°C kilocalories E(kcal20) is equal to the energy in kilojoules E(kJ) divided by 4.182:

E(kcal20) = E(kJ) / 4.182

Example

Convert 5 kilojoules to kilocalories.

E(kcal20) = 5 kJ / 4.182 = 1.196 kcal20
