Kilowatt/Square Metre

The kilowatt per square metre (kW/m²) equals 1000 W/m² and is used in concentrated solar power systems, industrial furnaces, and high-intensity thermal processes. It is a convenient unit for large heat flux values encountered in industrial heating and renewable energy applications. 


Watt/Square Metre

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.
