unit:BTU_TH-PER-LB
  a qudt:Unit ;
  dcterms:description "${\\bf Btu_{th} / lbm}$, British Thermal Unit (therm.) Per Pound Mass, is a unit in the category of total energy per unit mass, commonly known as specific enthalpy. It is also known as Btu per pound, Btu/pound, Btu/lb. This unit is commonly used in the UK unit system. British Thermal Unit (therm.) Per Pound Mass (Btu (therm.)/lbm) has a dimension of $L^2T^{-2}$ where $L$ is length, and $T$ is time. It can be converted to the corresponding standard SI unit J/kg by multiplying its value by a factor of 2324.443861."^^qudt:LatexString ;
