Convert Celsius Heat Unit per pound per degree Celsius to Joule per kilogram kelvin
Convert Celsius Heat Unit per pound per degree Celsius (CHU/(lb·°C)) to Joule per kilogram kelvin (J/(kg·K)) instantly and accurately.
Conversion Formula
J/(kg·K) = CHU/(lb·°C) × 4186.8
About Celsius Heat Unit per pound per degree Celsius
The Celsius heat unit per pound per degree Celsius (CHU/(lb·°C)) equals exactly (1055.05585262 × 9)/(0.45359237 × 5) J/(kg·K) = 4186.8 J/(kg·K). The CHU is 9/5 BTU(IT); combined with a 1 °C instead of 1 °F interval the factor is the same as BTU(IT)/(lb·°F). Used in older UK and Canadian engineering practice. Water: 1 CHU/(lb·°C). 1 CHU/(lb·°C) = 4186.8 J/(kg·K).
About Joule per kilogram kelvin
The joule per kilogram kelvin (J/(kg·K)) is the SI coherent unit for specific heat capacity, defined by the relation Q = mcΔT. Water ≈4182, iron ≈449, aluminium ≈897, copper ≈385, glass ≈840 J/(kg·K). Referenced in ISO 31-4 and all major international standards. 1 J/(kg·K) = 1 J/(kg·°C) = 10⁻³ kJ/(kg·K).
