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() = (-)
