What is Kilojoule (kJ)?

Kilojoule is a unit of energy that is equal to 1000 joules.

1 kilojoule is equal to 1000 joules:

1kJ = 1000J

1 joule is equal to 1/1000 kilojoule:

1J = 0.001kJ

The energy E_(J) in joules (J) is equal to the energy E_(kJ) in kilojoules times 1000:

E_(J) = E_(kJ) × 1000

1 kilojoule is equal to 0.94781712 BTU_(IT):

1 kJ = 0.94781712 BTU_(IT)

The energy E_(BTU) in BTUs is equal to 0.94781712 times the energy E_(kJ) in kilojoules (kJ):

E_(BTU) = E_(kJ) / 1.05505585262 = 0.94781712 ⋅ E_(kJ)

1 kcal_th is equal to 4.184 kilojoules (kJ):

1 kcal_th = 4.184 kJ

The energy in kilojoules E_(kJ) is equal to the energy in kilocalories E_(kcal-th)divided by 4.184:

E_(kcal) = E_(kJ) / 4.184
