About Joule per Kilogram-Kelvin (J/(kg·K))

The SI unit of specific heat capacity — the energy needed to raise the temperature of 1 kg of material by 1 K. J/(kg·K) is the universal unit in thermodynamics and heat-transfer analysis. Water's specific heat, the highest of any common substance, is 4,186 J/(kg·K); air is about 1,005 J/(kg·K); most metals are 400–900 J/(kg·K). Every CFD solver, HVAC sizing tool, and thermal-mass calculation uses J/(kg·K) internally.

About Kilojoule per Kilogram-Kelvin (kJ/(kg·K))

A metric specific-heat unit equal to 1,000 J/(kg·K). Because most common substances have specific heats in the 0.3–5 kJ/(kg·K) range, many European and international thermodynamics textbooks default to kJ/(kg·K) to keep numbers human-readable. Water is 4.186 kJ/(kg·K); steel ~0.49 kJ/(kg·K); liquid nitrogen ~1.04 kJ/(kg·K). Steam tables and refrigerant property tables typically list values in kJ/(kg·K).
