0.000265 US Gallons (Water)
SwitchExplanation
The converter converts grams of Water into us gallons using one fixed density basis of 997 kg/m^3. The same density model is used in the calculator, common values, and mirror page so storage, batching, and material-planning checks stay aligned.
Approximate liquid water density near room temperature.

Water density and calculation basis
Water is represented in this table by a fixed reference density of 997 kg/m^3, equivalent to 0.997 g/cm^3. Approximate liquid water density near room temperature.
At this fixed reference, 1 liter of Water corresponds to 0.997 kg, while 1 kg corresponds to 1.003009 liters. Its table density is the same as the 997 kg/m^3 water reference used in this dataset.
Among the 17 fixed table records labeled Liquids, the nearest density to Water is Seawater at 1025 kg/m^3: an absolute difference of 28 kg/m^3 (2.8% relative to Water). 10 records have a lower fixed density and 6 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, volume is calculated as mass divided by density after normalizing the units to kilograms and cubic meters. The resulting page multiplier is 0.00026497 gal (US) per g.
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.
