Convert Thermochemical BTU per pound per degree Fahrenheit to Kilowatt-hour per kilogram kelvin

Convert Thermochemical BTU per pound per degree Fahrenheit (BTU(th)/(lb·°F)) to Kilowatt-hour per kilogram kelvin (kWh/(kg·K)) instantly and accurately.

From: Thermochemical BTU per pound per degree Fahrenheit (BTU(th)/(lb·°F))

To: Kilowatt-hour per kilogram kelvin (kWh/(kg·K))

Conversion Formula

kWh/(kg·K) = BTU(th)/(lb·°F) × 0.001162222222

About Thermochemical BTU per pound per degree Fahrenheit

The thermochemical BTU per pound per degree Fahrenheit (BTU(th)/(lb·°F)) equals exactly 4184 J/(kg·K) (derived: 1 BTU(th) = 1054.350264 J; /lb/°F). Numerically identical to cal(th)/(g·°C) because both are defined via the thermochemical calorie. Used in older American thermodynamic tables. Water ≈1 BTU(th)/(lb·°F). 1 BTU(th)/(lb·°F) = 4184 J/(kg·K).

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).
