Exact conversion factors in both directions, plus a worked example.
1 J/(kg·K) = 0.001 kJ/(kg·K)
1 kJ/(kg·K) = 1000 J/(kg·K)
To convert joule per kilogram kelvin to kilojoule per kilogram kelvin, multiply by 0.001.
To convert kilojoule per kilogram kelvin to joule per kilogram kelvin, multiply by 1000.
Example: convert 10 J/(kg·K) to kJ/(kg·K)
10 × 0.001 = 0.01 kJ/(kg·K)
Short background on the units used in this conversion.
The joule per kilogram kelvin (J/(kg·K)) is the SI unit of specific heat capacity — energy required to raise one kilogram by one kelvin.
Joules per kilogram kelvin rate materials, fluids, and solids in engineering heat-transfer and energy storage calculations.
A kilojoule per kilogram kelvin (kJ/(kg·K)) equals 1,000 J/(kg·K) — convenient for metals and high-capacity thermal storage media.
Kilojoules per kilogram kelvin rate phase-change materials, molten salts, and concentrated thermal buffers.
kJ/(kg·K) = J/(kg·K) × 0.001J/(kg·K) = kJ/(kg·K) × 1,000, using the same exact factors as this converter.Jump to any specific heat capacity conversion starting from joule per kilogram kelvin — including the reverse direction and every other unit in our dataset.
