Common Specific Heat Capacity Conversions

• 1 J/(kg·K) = 1 J/(kg·°C) (exact: 1 K = 1 °C for temperature intervals)
• 1 kJ/(kg·K) = 1000 J/(kg·K) = 1 kJ/(kg·°C)
• 1 Wh/(kg·K) = 3600 J/(kg·K); 1 kWh/(kg·K) = 3.6 × 10⁶ J/(kg·K)
• 1 cal(th)/(g·°C) = 4184 J/(kg·K) (exact) = 1 kcal(th)/(kg·°C) = 1 BTU(th)/(lb·°F)
• 1 cal(IT)/(g·°C) = 4186.8 J/(kg·K) (exact) = 1 kcal(IT)/(kg·°C) = 1 BTU(IT)/(lb·°F) = 1 CHU/(lb·°C)
• 1 BTU(IT)/(lb·°F) ≈ 4186.8 J/(kg·K); 1 J/(kg·K) ≈ 2.3885 × 10^-4 BTU(IT)/(lb·°F)
• Water: 4182 J/(kg·K) ≈ 4.182 kJ/(kg·K) ≈ 1.000 BTU(IT)/(lb·°F) ≈ 0.999 cal(th)/(g·°C)
• Dry air: ≈1005 J/(kg·K); copper: ≈385 J/(kg·K); iron: ≈449 J/(kg·K); aluminium: ≈897 J/(kg·K)
