Btu (IT)/Hour/Square Foot

The British thermal unit (IT) per hour per square foot (Btu/(h·ft²)) equals approximately 3.155 W/m² and is the most common imperial unit of heat flux in North American HVAC and building engineering. It is used for heat loss calculations, U-values, and thermal performance ratings of building envelopes. 


Kilocalorie (IT)/Hour/Square Metre

The kilocalorie (IT) per hour per square metre (kcal/(h·m²)) equals approximately 1.163 W/m². It is used in older European engineering standards and building physics for expressing heat flux through walls, floors, and ceilings. Common in older HVAC and building energy standards.
