Convert Kilowatt-hour per kilogram kelvin to International table BTU per pound per degree Fahrenheit
Convert Kilowatt-hour per kilogram kelvin (kWh/(kg·K)) to International table BTU per pound per degree Fahrenheit (BTU(IT)/(lb·°F)) instantly and accurately.
Conversion Formula
BTU(IT)/(lb·°F) = kWh/(kg·K) × 859.8452279
About Kilowatt-hour per kilogram kelvin
The kilowatt-hour per kilogram kelvin (kWh/(kg·K)) equals exactly 3.6 × 10⁶ J/(kg·K). Used in large-scale thermal energy storage design - molten salt storage, geothermal reservoirs, and industrial heat banks - where energy is measured in megawatt-hours. 1 kWh/(kg·K) = 3.6 MJ/(kg·K) = 1000 Wh/(kg·K) = 3.6 × 10⁶ J/(kg·K).
About International table BTU per pound per degree Fahrenheit
The international table BTU per pound per degree Fahrenheit (BTU(IT)/(lb·°F)) equals (1055.05585262 × 9)/(0.45359237 × 5) J/(kg·K) = 4186.8 J/(kg·K). The standard US unit for specific heat capacity in ASHRAE, ASTM, and mechanical engineering references. Water: 1.000 BTU(IT)/(lb·°F); steel: ≈0.108; air: ≈0.240. 1 BTU(IT)/(lb·°F) = 4186.8 J/(kg·K).
