About Converting Ounce per Cubic inches to Grams per Gallon
Ounce per Cubic inch 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 = ounce per cubic inches × 6548.73984188
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per cubic inch equals 1729.99404439 base units, and 1 gram per gallon equals 0.264172052358 base units, so dividing one by the other gives the direct ounce per cubic inch-to-gram per gallon factor of 6548.73984188.
Simple example
1 oz/in3 × 6548.739842 = 6,548.739842 g/gal
1 ounce per cubic inch = 6,548.739842 grams per gallon.

What is a ounce per cubic inch?
Ounce per Cubic inch (oz/in3) is a unit of density.
What is a gram per gallon?
Gram per Gallon (g/gal) is a unit of density.
Is the ounce per cubic inch to gram per gallon conversion exact?
