How to transform from kcal to joules

Thermochemical / meals kilocalories to joules

1 kcal_th = 4184 J

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

E_(J) = 4184 &instances; E_(kcal-th)

Example

Convert 0.Three kcal_th to joules.

E_(J) = 4184 &instances; 0.Three kcal_th = 1255.2 J

International kilocalories to joules

1 kcal_IT = 4186.Eight J

The strength in joules E_(J) is same to 4186.Eight instances the electricity in worldwide kilocalories E_(kcal-IT):

E_(J) = 4186.Eight &instances; E_(kcal-IT)

Example

Convert zero.3 kcal_IT to joules.

E_(J) = 4186.Eight &instances; 0.3kcal_IT = 1256.04 J

15°C kilocalories to joules

1 kcal₁₅ = 4185.Five J

The energy in joules E_(J) is equal to 4185.Five times the energy in 15°C kilocalories E_(kcal15):

E_(J) = 4185.Five &instances; E_(kcal15)

Example

Convert zero.Three kcal₁₅ to joules.

E_(J) = 4185.Five &instances; 0.3kcal₁₅ = 1255.Sixty five J

20°C kilocalories to joules

1 kcal₂₀ = 4182 J

The electricity in joules E_(J) is identical to 4182 instances the strength in 20°C kilocalories E_(kcal20):

E_(J) = 4182 &instances; E_(kcal20)

Example

Convert 0.Three kcal₂₀ to joules.

E_(J) = 4182 × zero.3kcal₂₀ = 1254.6 J
