How to Convert Joule/Kilogram-Kelvin to Kilojoule/Kilogram-Kelvin

To convert from Joule/Kilogram-Kelvin (J/(kg·K)) to Kilojoule/Kilogram-Kelvin (kJ/(kg·K)), multiply the value by 0.001.

Formula: kJ/(kg·K) = J/(kg·K) × 0.001

Reverse: J/(kg·K) = kJ/(kg·K) × 1,000

Step-by-Step Example

Start with your value in Joule/Kilogram-Kelvin. For example: 5 J/(kg·K)
Multiply by the conversion factor: 5 x 0.001
The result is: 0.005 kJ/(kg·K)

About Joule/Kilogram-Kelvin

The joule/kilogram-kelvin (J/(kg·K)) is a unit of specific heat capacity. One joule/kilogram-kelvin equals 1 base unit. UnitConvertLab converts it against every other specific heat capacity unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: specific heat capacity calculations, engineering and science, education.
