Here is a similar formula from the 67th edition of the CRC handbook. Note that the form of this formula as given is a fit to the Clausius-Clapeyron equation, which is a good theoretical starting point for calculating saturation vapor pressures:
- log10(P) = -(0.05223)a/T + b, where P is in mmHg, T is in kelvins, a = 38324, and b = 8.8017.

Properties of aqueous methanol solutions
Data obtained from Lange's Handbook of Chemistry, 10th ed. and CRC Handbook of Chemistry and Physics 44th ed. The annotation, d a°C/b°C, indicates density of solution at temperature a divided by density of pure water at temperature b known as specific gravity. When temperature b is 4°C, density of water is 0.999972 g/mL.
