R-Value (imperial) (°F-ft2-h/Btu (therm.)) is a unit in the category of Thermal resistance coefficient. This unit is commonly used in the UK, US unit systems. R-Value (imperial) (°F-ft2-h/Btu (therm.)) has a dimension of M-1T3Q where M is mass, T is time, and Q is temperatur. It can be converted to the corresponding standard SI unit K-m2/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-m2/W), RSI (metric R-Value) (RSI), and Tog (tog).
