Convert Kilojoules per Kilogram Kelvin to J/(g·K)
1 kilojoule per kilogram kelvin (kJ/(kg·K)) = 1 joule per gram kelvin (J/(g·K)). 1 J/(g·K) = 1 kJ/(kg·K). Example: 15 kJ/(kg·K) = 15 × 1 = 15 J/(g·K).

How to Convert Kilojoule per Kilogram Kelvin to Joule per Gram Kelvin
- 1 kJ/(kg·K) = 1 J/(g·K)
- 1 J/(g·K) = 1 kJ/(kg·K)
- Example: convert 15 kJ/(kg·K) to J/(g·K): 15 kJ/(kg·K) = 15 × 1 J/(g·K) = 15 J/(g·K)
Formula
J/(g·K) = kJ/(kg·K) × 1
Derivation from SI units:
- 1 kJ/(kg·K) = 1000 J/(kg·K).
- 1 J/(g·K) = 1000 J/(kg·K) = 1 kJ/(kg·K).
- 1 kJ/(kg·K) = 1000 J/(kg·K) ÷ 1000 J/(kg·K) per J/(g·K) = 1 J/(g·K)
Both units are defined exactly, so the factor is exact. Kilojoule per Kilogram Kelvin definition: kilojoule per kilogram kelvin; Joule per Gram Kelvin definition: joule per gram kelvin.
Worked examples
- A reading of 0.84 kJ/(kg·K) converts to 0.84 J/(g·K).
0.84 kJ/(kg·K) × 1 = 0.84 J/(g·K) - A value of 1.7 kJ/(kg·K) is 1.7 J/(g·K).
1.7 kJ/(kg·K) × 1 = 1.7 J/(g·K)
