Kilojoule per Kilogram Kelvin (kJ/(kg·K))
Kilojoules per kilogram kelvin are the working unit of thermodynamics tables and GATE questions: cp of air 1.005 kJ/(kg·K), water 4.187, steam about 2.0.
Symbol: kJ/(kg·K) (ASCII: kJ/(kg K))
Quantity: specific heat capacity
SI relation: 1 kJ/(kg·K) = 1000 J/(kg·K) (exact)
Derivation: 1 kJ/(kg·K) = 1000 J/(kg·K).
Exact: yes, by definition
Same quantity as joule per gram kelvin (J/(g·K)) : the factor between them is exactly 1.
Typical uses
- Steam and air tables
- Thermodynamics and heat-transfer problems
- Food and process engineering
