**R-Value (imperial)**

**R-Value (imperial) (°F-ft**is a unit in the category of

^{2}-h/Btu (therm.))*Thermal resistance coefficient*. This unit is commonly used in the UK, US unit systems. R-Value (imperial) (°F-ft

^{2}-h/Btu (therm.)) has a dimension of M

^{-1}T

^{3}Q where M is mass, T is time, and Q is temperatur. It can be converted to the corresponding standard SI unit K-m

^{2}/W by multiplying its value by a factor of 0.176228083653.

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 Thermal resistance coefficient include Clo (clo), Kelvin Meter Squared Per Watt (K-m^{2}/W), RSI (metric R-Value) (RSI), and Tog (tog).
