About Converting Stones per Quart to Slugs per Gallon
Stone per Quart and Slug 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
slugs per gallon = stones per quart × 1.74053320961
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per quart equals 6710.27992975 base units, and 1 slug per gallon equals 3855.30129084 base units, so dividing one by the other gives the direct stone per quart-to-slug per gallon factor of 1.74053320961.
Simple example
1 st/qt × 1.74053321 = 1.74053321 slug/gal
1 stone per quart = 1.74053321 slugs per gallon.
Real-world example
1,000 st/qt × 1.74053321 = 1,740.53321 slug/gal
1,000 stones per quart = 1,740.53321 slugs per gallon.

What is a stone per quart?
Stone per Quart (st/qt) is a unit of density.
What is a slug per gallon?
Slug per Gallon (slug/gal) is a unit of density.
Is the stone per quart to slug per gallon conversion exact?
Yes. Both stone per quart and slug per gallon are defined by fixed standards rather than physical artifacts, so the factor of 1.74053321 used above is exact to as many digits as you choose to display.
