**British Thermal Unit (therm.) Per Second**

**British Thermal Unit (therm.) Per Second (Btu (therm.)/s)**is a unit in the category of

*Power (Heat flow)*. It is also known as Btu per second, Btu/second. This unit is commonly used in the UK, US unit systems. British Thermal Unit (therm.) Per Second (Btu (therm.)/s) has a dimension of ML

^{2}T

^{-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 1054.35.
