  • 1 J/(kg K) = 2.389x10-4 kcal/(kg oC) = 2.389x10-4 Btu/(lbm oF)
  • 1 kJ/(kg K) = 0.2389 kcal/(kg oC) = 0.2389 Btu/(lbm oF)
  • 1 Btu/(lbm oF) = 4,186.8 J/ (kg K) = 1 kcal/(kg oC)
  • 1 kcal/(kg oC) = 4,186.8 J/ (kg K) = 1 Btu/(lbm oF)

Example - Heating Carbon Steel

2 kg of carbon steel is heated from 20 oC to 100 oC. Specific heat of carbon steel is 0.49 kJ/kg0C and the heat required can be calculated as

dQ = 2 (kg) 0.49 (kJ/kg0C) (100 (oC) - 20 (oC)) 

     = 78.4 (kJ)
