Small and large calories

A small calorie is the energy required to raise 1 gram of water by 1°C at a pressure of 1 atmosphere.

Large Calorie (cal) is the energy required to raise 1 kg of water by 1 degree Celsius at a pressure of 1 atmosphere.

Large calorie is also called food calorie and is used as a unit of food energy.

How to convert calories to kilojoules

Thermochemical Calorie to Kilojoule

1 calth = 0.004184 kJ

2 calth = 0.008.368 kJ

5 calth = 0.0020.92 kJ

1 kJ = 239.005736 calth

So The energy in kilojoules E(kJ) is equal to the energy in thermochemical calorie E(calth) divided by 239.005736.

E(kJ) = E(calth) / 239.005736

Example 1

Convert 100 calth to kilojoules.

E(kJ) = 100calth / 239.005736 = 0.4184 kJ

Example 2

Convert 1000 calth to kilojoules.

E(kJ) = 1000calth / 239.005736 = 4.184 kJ

Example 3

Convert 10000 calth to kilojoules.

E(kJ) = 10000calth / 239.005736 = 41.84 kJ

15°C calories to kJ

1 cal15 = 0.0041855 kJ

2 cal15 = 0.008371 kJ

5 cal15 = 0.0209275 kJ

1 kJ = 238.9201 cal15

So The energy in kilojoules E(kJ) at 15 °C is equal to the energy in calorie e E(cal15) divided by 238.9201.

E(kJ) = E(cal15) / 238.9201

Example 1

Convert 100 cal15 to kilojoules.

E(kJ) = 100cal15 / 238.9201 = 0.41855 kJ

Example 2

Convert 1000 cal15 to kilojoules.

E(kJ) = 1000cal15 / 238.9201 = 4.1855 kJ

Example 3

Convert 10000 cal15 to kilojoules.

E(kJ) = 10000cal15 / 238.9201 = 41.855 kJ

Large/food calories to kJ

1 Cal = 4.184 kJ

2 Cal = 8.368 kJ

5 Cal = 20.92 kJ

1 kJ = 0.239 Cal

So The energy in kilojoules E(kJ) is equal to 4184 times the energy in large/food calories E(Cal).

E(kJ) = 4.184 × E(calth)

Example 1

Convert 1.1 Cal to kilojoules.

E(kJ) = 4.184 × 1.1 Cal = 4.6024 kJ

Example 2

Convert 2.5 Cal to kilojoules.

E(kJ) = 4.184 × 2.5 Cal = 10.46 kJ

Example 3

Convert 3 Cal to kilojoules.

E(kJ) = 4.184 × 3 Cal = 12.552 kJ
