How to convert from kcal to joules

Thermochemical / food kilocalories to joules

1 kcal_th = 4184 J

The energy in joules E_(J) is equal to 4184 times the energy in thermochemical / food kilocalories E_(kcal):

E_(J) = 4184 × E_(kcal-th)

Example

Convert 0.3 kcal_th to joules.

E_(J) = 4184 × 0.3 kcal_th = 1255.2 J

International kilocalories to joules

1 kcal_IT = 4186.8 J

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

E_(J) = 4186.8 × E_(kcal-IT)

Example

Convert 0.3 kcal_IT to joules.

E_(J) = 4186.8 × 0.3kcal_IT = 1256.04 J

15ºC kilocalories to joules

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_(J) = 4185.5 × E_(kcal15)

Example

Convert 0.3 kcal₁₅ to joules.

E_(J) = 4185.5 × 0.3kcal₁₅ = 1255.65 J

20ºC kilocalories to joules

1 kcal₂₀ = 4182 J

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

E_(J) = 4182 × E_(kcal20)

Example

Convert 0.3 kcal₂₀ to joules.

E_(J) = 4182 × 0.3kcal₂₀ = 1254.6 J
