Small & massive calories

Small calorie (cal) is the electricity needed to growth 1 gram of water by way of the usage of 1°C at a pressure of one surroundings.

Large calorie (Cal) is the power had to boom 1 kg of water with the resource of way of 1°C at a stress of 1 environment.

Large calorie is also known as food calorie and is used as a unit of food strength.

How to convert from strength to kilojoules

Thermochemical energy to kJ

1 cal_th = 0.004184 kJ

1 kJ = 239.005736 cal_th

The strength in kilojoules E_(kJ) is equal to the power in thermochemical energy E_(calth) divided by 239.005736:

E_(kJ) = E_(calth) / 239.005736

Example

Convert three hundred cal_th to kilojoules.

E_(kJ) = 300cal_th / 239.005736 = 1.2552 kJ

15°C electricity to kJ

1 cal₁₅ = 0.0041855 kJ

1 kJ = 238.9201 cal₁₅

The electricity in kilojoules E_(kJ) is identical to the electricity in 15°C power E_(cal15) divided via 238.9201:

E_(kJ) = E_(cal15) / 238.9201

Example

Convert 3 hundred cal₁₅ to kilojoules.

E_(kJ) = 300cal₁₅ / 238.9201 = 1.25565 kJ

Large/food electricity to kJ

1 Cal = four.184 kJ

1 kJ = 0.239 Cal

The strength in kilojoules E_(kJ) is identical to 4184 instances the energy in big/food energy E_(Cal):

E_(kJ) = 4.184 × E_(calth)

Example

Convert zero.Three Cal to kilojoules.

E_(kJ) = four.184 × zero.Three Cal = 1.2552 kJ
