How to convert from joules to kcal

Joules to thermochemical / food kilocalories

1 kcalth = 4184 J

The energy in joules E(J) is equal to the energy in kilocalories E(kcal-th) divided by 4184:

E(kcal) = E(J) / 4184

Example

Convert 5000 joules to kilocalories.

E(kcal) = 5000 J / 4184 = 1.195 kcal

Joules to international kilocalories

1 kcalIT = 4186.8 J

The energy in joules E(J) is equal to 4186.8 times the energy in international kilocalories E(kcal-IT):

E(kcal-IT) = E(J) / 4186.8

Example

Convert 5000 joules to kilocalories.

E(kcal-IT) = 5000 J / 4186.8 = 1.194 kcalIT

Joules to 15ºC kilocalories

1 kcal15 = 4185.5 J

The energy in joules E(J) is equal to 4185.5 times the energy in 15ºC kilocalories E(kcal15):

E(kcal15) = E(J) / 4185.5

Example

Convert 5000 joules to kilocalories.

E(kcal15) = 5000 J / 4185.5 = 1.195 kcal15

Joules to 20ºC kilocalories

1 kcal20 = 4182 J

The energy in joules E(J) is equal to 4182 times the energy in 20ºC kilocalories E(kcal20):

E(kcal20) = E(J) / 4182

Example

Convert 5000 joules to kilocalories.

E(kcal20) = 5000 J / 4182 = 1.196 kcal20
