Convert btu (it)/minute/square foot to watt/square meter
Btu (IT)/Minute/Square Foot
The British thermal unit (IT) per minute per square foot (Btu/(min·ft²)) equals approximately 189.3 W/m². It is an intermediate imperial unit of heat flux used in fire safety engineering, process heating, and North American industrial standards where per-minute time scales are convenient.
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.
