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:

The modern low pressure methanol (LPM) process was developed by ICI in the late 1960s US 3326956 with the technology patent long since expired. During World War II , methanol was used as a fuel in several German military rocket designs, under the name M-Stoff , and in a roughly 50/50 mixture with hydrazine , known as C-Stoff .
Until 1982, STP was defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of 101.325 kPa (1 atm). Since 1982, STP is defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of 100 kPa (1 bar). Conversions between each volume flow metric are calculated using the following formulas: Prior to 1982,
One liter of ethanol releases 21.1 MJ in combustion, a liter of methanol 15.8 MJ and a liter of gasoline approximately 32.6 MJ. In other words, for the same energy content as one liter or one gallon of gasoline, one needs 1.6 liters/gallons of ethanol and 2.1 liters/gallons of methanol.
Methanol is produced during the brewing process and concentrated by distillation. Commercial manufacturers will reduce it to levels which are safe for human consumption.
