British Thermal Unit (IT) Per Hour Per Square Foot (Btu (IT)/h-ft²) is a unit in the category of Energy flux. This unit is commonly used in the UK, US unit systems. British Thermal Unit (IT) Per Hour Per Square Foot (Btu (IT)/h-ft²) has a dimension of MT^-3 where M is mass, and T is time. It can be converted to the corresponding standard SI unit W/m² by multiplying its value by a factor of 3.154590743.

Note that the seven base dimensions are M (Mass), L (Length), T (Time), Q (Temperature), N (Aamount of Substance), I (Electric Current), and J (Luminous Intensity).

Other units in the category of Energy flux include British Thermal Unit (therm.) Per Hour Per Square Foot (Btu (therm.)/h-ft²), Langley (flux) (ly), and Watt Per Square Meter (W/m²).
