Convert btu (it)/second/square foot to btu (it)/hour/square foot
Btu (IT)/Second/Square Foot
The British thermal unit (IT) per second per square foot (Btu/(s·ft²)) equals approximately 11,356 W/m². It is an imperial unit used for high-intensity heat fluxes such as those encountered in rocket nozzles, re-entry vehicles, and high-power industrial burners in North American engineering.
Btu (IT)/Hour/Square Foot
The British thermal unit (IT) per hour per square foot (Btu/(h·ft²)) equals approximately 3.155 W/m² and is the most common imperial unit of heat flux in North American HVAC and building engineering. It is used for heat loss calculations, U-values, and thermal performance ratings of building envelopes.
