Convert btu (it)/second/square foot to watt/square meter
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.
Watt/Square Meter
The watt per square metre (W/m²) is the SI unit of heat flux density and irradiance. It represents the power transmitted per unit area. The solar constant (total solar irradiance) at Earth's orbit is approximately 1361 W/m². Used in heat transfer engineering, solar energy, and thermal radiation analysis.
