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).
About BTU per Pound-Fahrenheit (BTU/(lb·°F))
An imperial specific-heat unit widely used in US HVAC, petroleum engineering, and thermodynamics. By the BTU's definition, water has a specific heat of 1 BTU/(lb·°F). US steam tables, ASHRAE HVAC calculations, and petroleum reservoir simulations all use BTU/(lb·°F). Converting to SI (×4,186.8 to get J/(kg·K)) is routine for international engineering collaboration.
