EngCoolProp Interfaces The Coolprop Project with English Units¶
CoolProp uses SI units for calculating fluid properties. For those of us in industries that rely on English/Engineering units, EngCoolProp provides an interface.

EngCoolProp uses units of primarily inch, lbm, lbf, sec, BTU (some use of ft and hour).:
The following are the default units for each property. T = Temperature = degR Tc = Critical Temperature = degR Tnbp = Normal Boiling Point = degR P = Pressure = psia Pc = Critical Pressure = psia D = Density = lbm/cu ft rho = Density = lbm/cu inch Dc = Critical Density = lbm/cu ft E = Internal Energy = BTU/lbm H = Enthalpy = BTU/lbm S = Entropy = BTU/lbm degR Cv = Heat Capacity (const. V) = BTU/lbm degR Cp = Heat Capacity (const. P) = BTU/lbm degR g = Ratio of Specific Heats (Cp/Cv) = (-) A = Sonic Velocity = ft/sec V = Viscosity = 1.0E5 * lb/ft-sec C = Thermal Conductivity = BTU/ft-hr-R MW = Molecular Weight = lbm/lbmmole Q = Quality (fraction gas) = (-) Z = Compressibility() = (-)
