Convert Joules per Kilogram Kelvin to Joules per Gram Kelvin
1 joule per kilogram kelvin (J/(kg·K)) = 0.001 joules per gram kelvin (J/(g·K)). 1 J/(g·K) = 1000 J/(kg·K). Example: 15 J/(kg·K) = 15 × 0.001 = 0.015 J/(g·K).

How to Convert Joule per Kilogram Kelvin to Joule per Gram Kelvin
- 1 J/(kg·K) = 0.001 J/(g·K)
- 1 J/(g·K) = 1000 J/(kg·K)
- Example: convert 15 J/(kg·K) to J/(g·K): 15 J/(kg·K) = 15 × 0.001 J/(g·K) = 0.015 J/(g·K)
Formula
J/(g·K) = J/(kg·K) ÷ 1000
Derivation from SI units:
- Heat per unit mass per kelvin: J/(kg·K) (a kelvin step equals a degree Celsius step).
- 1 J/(g·K) = 1000 J/(kg·K) = 1 kJ/(kg·K).
Both units are defined exactly, so the factor is exact. Joule per Kilogram Kelvin definition: joule per kilogram kelvin; Joule per Gram Kelvin definition: joule per gram kelvin.
Worked examples
- A reading of 500 J/(kg·K) converts to 0.5 J/(g·K).
500 J/(kg·K) × 0.001 = 0.5 J/(g·K) - A value of 1005 J/(kg·K) is 1.005 J/(g·K).
1005 J/(kg·K) × 0.001 = 1.005 J/(g·K)

Where it's used
Joules per Kilogram Kelvin are used for sensible heat Q = m c ΔT, while joules per gram kelvin appear in calorimetry in chemistry. Both measure specific heat capacity, so the conversion is a fixed factor.

Frequently asked questions
How many joules per gram kelvin are in 1 joule per kilogram kelvin?
1 J/(kg·K) = 0.001 J/(g·K).
How do I convert joules per kilogram kelvin to joules per gram kelvin?
Multiply the value in J/(kg·K) by 0.001, or divide it by 1000. For example, 15 J/(kg·K) × 0.001 = 0.015 J/(g·K).
Is the J/(kg·K) to J/(g·K) conversion exact?
Yes. Both units are defined exactly, and 1 J/(kg·K) is exactly 0.001 J/(g·K).
