Per Hour (Btu (therm.)/h) is a unit in the category of Power (Heat flow). It is also known as Btu per hour, Btu/hour, btu/hr. This unit is commonly used in the UK, US unit systems. British Thermal Unit (therm.) Per Hour (Btu (therm.)/h) has a dimension of ML2T-3 where M is mass, L is length, and T is time. It can be converted to the corresponding standard SI unit W by multiplying its value by a factor of 0.292875.
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).
