Small & big calories

Small calorie (cal) is the strength had to increase 1 gram of water by means of the use of 1°C at a stress of 1 atmosphere.

Large calorie (Cal) is the electricity needed to growth 1 kg of water with the aid of manner of 1°C at a pressure of 1 surroundings.

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

How to convert from energy to kilojoules

Thermochemical calories to kJ

1 cal_th = 0.004184 kJ

1 kJ = 239.005736 cal_th

The electricity in kilojoules E_(kJ) is same to the energy in thermochemical strength E_(calth) divided by means of 239.005736:

E_(kJ) = E_(calth) / 239.005736

Example

Convert 300 cal_th to kilojoules.

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

15°C energy to kJ

1 cal₁₅ = 0.0041855 kJ

1 kJ = 238.9201 cal₁₅

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

E_(kJ) = E_(cal15) / 238.9201

Example

Convert three hundred cal₁₅ to kilojoules.

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

Large/food energy to kJ

1 Cal = four.184 kJ

1 kJ = zero.239 Cal

The energy in kilojoules E_(kJ) is same to 4184 times the energy in massive/meals calories E_(Cal):

E_(kJ) = four.184 &instances; E_(calth)

Example

Convert 0.Three Cal to kilojoules.

E_(kJ) = 4.184 × zero.Three Cal = 1.2552 kJ
