Convert Kilojoules per Kilogram Kelvin to J/(kg·K)
1 kilojoule per kilogram kelvin (kJ/(kg·K)) = 1000 joules per kilogram kelvin (J/(kg·K)). 1 J/(kg·K) = 0.001 kJ/(kg·K). Example: 15 kJ/(kg·K) = 15 × 1000 = 15000 J/(kg·K).

How to Convert Kilojoule per Kilogram Kelvin to Joule per Kilogram Kelvin
- 1 kJ/(kg·K) = 1000 J/(kg·K)
- 1 J/(kg·K) = 0.001 kJ/(kg·K)
- Example: convert 15 kJ/(kg·K) to J/(kg·K): 15 kJ/(kg·K) = 15 × 1000 J/(kg·K) = 15000 J/(kg·K)
Formula
J/(kg·K) = kJ/(kg·K) × 1000
Derivation from SI units:
- 1 kJ/(kg·K) = 1000 J/(kg·K).
- Heat per unit mass per kelvin: J/(kg·K) (a kelvin step equals a degree Celsius step).
Both units are defined exactly, so the factor is exact. Kilojoule per Kilogram Kelvin definition: kilojoule per kilogram kelvin; Joule per Kilogram Kelvin definition: joule per kilogram kelvin.
Worked examples
- A reading of 0.84 kJ/(kg·K) converts to 840 J/(kg·K).
0.84 kJ/(kg·K) × 1000 = 840 J/(kg·K) - A value of 1.7 kJ/(kg·K) is 1700 J/(kg·K).
1.7 kJ/(kg·K) × 1000 = 1700 J/(kg·K)

Where it's used
Kilojoules per Kilogram Kelvin are used for steam and air tables, while joules per kilogram kelvin appear in sensible heat Q = m c ΔT. Both measure specific heat capacity, so the conversion is a fixed factor.
