Joule per kilogram to kilojoule per kilogram Conversion
1 joule per kilogram (J/kg) is equal to 0.001 kilojoule per kilogram (kJ/kg).
1 J/kg = 0.001 kJ/kg
or
1 kJ/kg = 1000 J/kg
Formula
To convert a specific energy from joule per kilogram (J/kg) to kilojoule per kilogram (kJ/kg), divide the specific energy in joule per kilogram by 1000
s(kJ/kg) = s(J/kg) / 1000
Examples:
Convert 1000 joule per kilogram to kilojoule per kilogram:
s(kJ/kg) = 1000J/kg / 1000 = 1 kJ/kg
