1 British thermal unit per pound-degree Fahrenheit (Btu/lb⋅°F) is equal to 4184 joule per kilogram-kelvin (J/kg⋅K).
1 Btu/lb⋅°F = 4184 J/kg⋅K
or
1 J/kg⋅K = 0.0002390057361 Btu/lb⋅°F
Formula
To convert a specific heat capacity from British thermal unit per pound-degree Fahrenheit (Btu/lb⋅°F) to joule per kilogram-kelvin (J/kg⋅K), multiply the specific heat capacity in British thermal unit per pound-degree Fahrenheit by 4184
s(J/kg⋅K) = s(Btu/lb⋅°F) × 4184
Examples:
Convert 500 British thermal unit per pound-degree Fahrenheit to joule per kilogram-kelvin:
s(J/kg⋅K) = 500Btu/lb⋅°F × 4184 = 2092000 J/kg⋅K
