Explanation

Formula: BTU per pound-degree Fahrenheit = Joules per kilogram-kelvin × 0.000239. Why: the route normalizes to joules per kilogram-kelvin, then applies the fixed BTU energy definition, the pound mass definition, and the Fahrenheit-to-kelvin interval scaling.

Joules per kilogram-kelvin (J/(kg·K)): the standard SI-style specific heat capacity unit expressing how many joules are needed to raise one kilogram by one kelvin.

BTU per pound-degree Fahrenheit (BTU/(lb·°F)): an imperial engineering heat-capacity unit used in HVAC, combustion, and US thermal property references.

This route is useful when comparing SI thermal property data with US engineering or HVAC references that report specific heat in BTU per pound per degree Fahrenheit.

This conversion is purely multiplicative because both units reduce through one joules-per-kilogram-kelvin basis, and temperature intervals are handled as fixed scale relationships with no offset term.
