About Converting Troy ounces per Gallon to Grams per Gallon
Troy ounce per Gallon 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 = troy ounces per gallon × 31.1034768
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per gallon equals 8.21666930173 base units, and 1 gram per gallon equals 0.264172052358 base units, so dividing one by the other gives the direct troy ounce per gallon-to-gram per gallon factor of 31.1034768.
Simple example
1 oz t/gal × 31.1034768 = 31.1034768 g/gal
1 troy ounce per gallon = 31.1034768 grams per gallon.
Real-world example
1,000 oz t/gal × 31.1034768 = 31,103.4768 g/gal
