About Converting Ounces per Quart to Grams per Imperial gallon
Ounce per Quart and Gram per Imperial 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 imperial gallon = ounces per quart × 136.18543074
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per quart equals 29.9566068292 base units, and 1 gram per imperial gallon equals 0.219969248299 base units, so dividing one by the other gives the direct ounce per quart-to-gram per imperial gallon factor of 136.18543074.
Simple example
1 oz/qt × 136.1854307 = 136.1854307 g/imp gal
1 ounce per quart = 136.1854307 grams per imperial gallon.
Real-world example
1,000 oz/qt × 136.1854307 = 136,185.4307 g/imp gal
1,000 ounces per quart = 136,185.4307 grams per imperial gallon.

What is a ounce per quart?
Ounce per Quart (oz/qt) is a unit of density.
What is a gram per imperial gallon?
Gram per Imperial gallon (g/imp gal) is a unit of density.
Is the ounce per quart to gram per imperial gallon conversion exact?
Yes. Both ounce per quart and gram per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 136.1854307 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
