Short background on the units used in this conversion.
The watt per square meter (W/m²) is the SI unit of heat flux density — instantaneous thermal power per unit area.
Watts per square meter describe convection, radiation, and conduction heat flow rates at surfaces in HVAC and electronics cooling.
A kilocalorie (IT) per hour square meter equals 1.163 W/m² — a calorie-based heat flux rate.
Kilocalories (IT) per hour square meter appear in metric HVAC and process heat transfer references.
kcal (IT)/(h·m²) = W/m² × 0.8598452279W/m² = kcal (IT)/(h·m²) × 1.163, using the same exact factors as this converter.Jump to any heat flux density conversion starting from watt per square meter — including the reverse direction and every other unit in our dataset.
