Specific Heat Converter
Specific heat capacity: J/(kg·K), kJ/(kg·K), J/(g·°C), cal/(g·°C) and BTU/(lb·°F). Calorie and BTU are International Table values unless marked thermochemical.
That is below absolute zero (−273.15 °C), which isn’t physically possible.
1 Joule per kilogram kelvin = 0.000238845897 BTU per pound °F
Formula: divide the specific heat value by 4,186.8
1 J/(kg·K) in every specific heat unit

How to convert specific heat units
Specific heat capacity: J/(kg·K), kJ/(kg·K), J/(g·°C), cal/(g·°C) and BTU/(lb·°F). Calorie and BTU are International Table values unless marked thermochemical. Every conversion goes through one base unit, the joule per kilogram kelvin, using exact factors, so results don’t drift.
Joules per kilogram kelvin to bTU per pound °F (J/(kg·K) to BTU/(lb·°F))
To convert joules per kilogram kelvin to bTU per pound °F, divide by 4,186.8. 1 joule per kilogram kelvin = 0.0002388459 bTU per pound °F.
