}Explanation
US Gallons of Ethanol convert to grams using one fixed density basis of 789 kg/m^3. The same density model is used in the calculator, common values, and mirror route so weight, mass, and volume checks stay aligned.
Typical pure ethanol density near room temperature.

Methodology
Ethanol density and calculation basis
Ethanol is represented in this table by a fixed reference density of 789 kg/m^3, equivalent to 0.789 g/cm^3. Typical pure ethanol density near room temperature.
At this fixed reference, 1 liter of Ethanol corresponds to 0.789 kg, while 1 kg corresponds to 1.267427 liters. Its table density is 20.9% lower than the 997 kg/m^3 water reference used in this dataset.
Among the 17 fixed table records labeled Liquids, the nearest density to Ethanol is Isopropyl Alcohol at 786 kg/m^3: an absolute difference of 3 kg/m^3 (0.4% relative to Ethanol). 3 records have a lower fixed density and 13 have a higher one. The observed range in this labeled group is Gasoline at 745 kg/m^3 to Honey at 1420 kg/m^3. This is a numerical comparison, not a claim that the materials are interchangeable.
For this direction, mass is calculated as volume multiplied by density after normalizing the units to cubic meters and kilograms. The resulting page multiplier is 2,986.69 g per gal (US).
The fixed value supports repeatable calculations but is not a batch, grade, supplier, or laboratory specification. Use a measured or certified density when those conditions control the result.
