WebbThe form of the Antoine equation used here is: log10(P) = A – [B / (T + C)], where P is the calculated vapor pressure in bar (on an absolute scale) and T is the temperature in Kelvin. Using the reference data assembled by NIST, you can plug in the values for A, B, and C to estimate the vapor pressure, P.
