About Converting Ounces per Fluid ounce to Grams per Gallon
Ounce per Fluid ounce and Gram per Gallon both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Both are mass per volume density units.
Formula
grams per gallon = ounces per fluid ounce × 3628.73896
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per fluid ounce equals 958.611418535 base units, and 1 gram per gallon equals 0.264172052358 base units, so dividing one by the other gives the direct ounce per fluid ounce-to-gram per gallon factor of 3628.73896.
Simple example
1 oz/fl oz × 3628.73896 = 3,628.73896 g/gal
1 ounce per fluid ounce = 3,628.73896 grams per gallon.
Real-world example
1,000 oz/fl oz × 3628.73896 = 3,628,738.96 g/gal
1,000 ounces per fluid ounce = 3,628,738.96 grams per gallon.
