Convert Kilojoule per kilogram degree Celsius to Thermochemical BTU per pound per degree Fahrenheit
Convert Kilojoule per kilogram degree Celsius (kJ/(kg·°C)) to Thermochemical BTU per pound per degree Fahrenheit (BTU(th)/(lb·°F)) instantly and accurately.
Conversion Formula
BTU(th)/(lb·°F) = kJ/(kg·°C) × 0.2390057361
About Kilojoule per kilogram degree Celsius
The kilojoule per kilogram degree Celsius (kJ/(kg·°C)) equals exactly 1 kJ/(kg·K) = 1000 J/(kg·K) since 1 °C = 1 K. The preferred notation in European process and chemical engineering where Celsius dominates. Often used interchangeably with kJ/(kg·K) in material datasheets. Water: 4.182 kJ/(kg·°C). 1 kJ/(kg·°C) = 1 kJ/(kg·K) = 1000 J/(kg·K).
About Thermochemical BTU per pound per degree Fahrenheit
The thermochemical BTU per pound per degree Fahrenheit (BTU(th)/(lb·°F)) equals exactly 4184 J/(kg·K) (derived: 1 BTU(th) = 1054.350264 J; /lb/°F). Numerically identical to cal(th)/(g·°C) because both are defined via the thermochemical calorie. Used in older American thermodynamic tables. Water ≈1 BTU(th)/(lb·°F). 1 BTU(th)/(lb·°F) = 4184 J/(kg·K).
