How to convert from joules to kcal

Joules to thermochemical / meals kilocalories

1 kcal_th = 4184 J

The power in joules E_(J) is identical to the strength in kilocalories E_(kcal-th) divided with the aid of way of 4184:

E_(kcal) = E_(J) / 4184

Example

Convert 5000 joules to kilocalories.

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

Joules to global kilocalories

1 kcal_IT = 4186.Eight J

The energy in joules E_(J) is same to the electricity in international kilocalories E_(kcal-IT) divided thru 4186.Eight:

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

Example

Convert 5000 joules to kilocalories.

E_(kcal-IT) = 5000 J / 4186.Eight = 1.194 kcal_IT

Joules to fifteen°C kilocalories

1 kcal₁₅ = 4185.Five J

The strength in joules E_(J) is same to the power in 15°C kilocalories E_(kcal15) divided via using 4185.Five:

E_(kcal15) = E_(J) / 4185.Five

Example

Convert 5000 joules to kilocalories.

E_(kcal15) = 5000 J / 4185.Five = 1.195 kcal₁₅

Joules to 20°C kilocalories

1 kcal₂₀ = 4182 J

The energy in joules E_(J) is equal to the electricity in 20°C kilocalories E_(kcal20) divided via way of 4182:

E_(kcal20) = E_(J) / 4182

Example

Convert 5000 joules to kilocalories.

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