What is Kilojoule (kJ)?

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

3 kilojoule is equal to 3000 joules:

Example 1

3kJ = 3000J

Example 2

5kJ = 5000J

Example 3

7kJ = 7000J

2 joule is equal to 2/1000 kilojoule:

Example 1

2J = 0.002kJ

Example 2

4J = 0.004kJ

Example 3

8J = 0.008kJ

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

E_(J) = E_(kJ) × 1000

2 kilojoule is equal to 1.89563424 BTU_(IT):

Example 1

2 kJ = 1.89563424 BTU_(IT)

Example 2

4 kJ = 3.79126849 BTU_(IT)

so 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

2 kcal_th = 8.368 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
