Kilocalorie (IT)/Hour/Square Foot

The kilocalorie (IT) per hour per square foot (kcal/(h·ft²)) is a hybrid metric-imperial unit of heat flux. It equals approximately 12.518 W/m² and is encountered in older technical literature and some international engineering calculations mixing metric energy with imperial area. 


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.
