Formula
BTU·in/(h·ft²·°F) = kcal/(h·m·°C) × 8.063627701674
Derivation from SI units:
- 1 kcal_IT/(h·m·°C) = 4186.8 J ÷ (3600 s × 1 m × 1 K) = 1.163 W/(m·K) (exact)
- 1 BTU_IT·in/(h·ft²·°F) = 1055.05585262 J × 0.0254 m ÷ (3600 s × 0.09290304 m² × 5/9 K) = 0.1442278889 W/(m·K) (exact)
- 1 kcal/(h·m·°C) = 1.163 W/(m·K) ÷ 0.1442278888643 W/(m·K) per BTU·in/(h·ft²·°F) = 8.063627701674 BTU·in/(h·ft²·°F)
Both units are defined exactly, so the factor is exact. kcal/(h·m·°C) definition: kilocalorie per hour metre degree Celsius; BTU·in/(h·ft²·°F) definition: BTU inch per hour square foot degree Fahrenheit.
