Full API documentation

Explanation

Formula: BTU per hour-foot-degree Fahrenheit = Watts per meter-kelvin × 0.577789. Why: the BTU-based engineering unit uses a fixed watts-per-meter-kelvin equivalent, so the calculator normalizes through W/(m·K) before applying the target unit.

Watts per meter-kelvin (W/(m·K)): the SI thermal-conductivity unit used in materials science, heat transfer, and engineering specifications.

BTU per hour-foot-degree Fahrenheit (BTU/(h·ft·°F)): an imperial/US engineering thermal-conductivity unit common in HVAC and building-material references.

This route is useful when comparing SI thermal-conductivity values with US engineering and HVAC references for insulation, building materials, and heat-transfer components.

This conversion is purely multiplicative because both units reduce through watts per meter-kelvin using fixed thermal-conductivity definitions with no offset.
