How to Converter energy in joules (J) to kilojoules (kJ).
One kilojoules is equal to 1000 joules:
1kJ = 1000J
The energy E in kilojoules (kJ) is equal to the energy in joules (J) divided by 1000:
E(kJ) = E(J) / 1000
Converter 400J to kilojoules.
The energy E in kilojoules (kJ) is equal to 400 joules (J) divided by 1000:
E(kJ) = 400J / 1000 = 0.4kJ
