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 kcalth is equal to 4.184 kilojoules (kJ):
1 kcalth = 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
