About Converting Long tons per Gallon to Slugs per Quart
Long ton per Gallon and Slug per Quart 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 quart = long tons per gallon × 17.4053320961
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per gallon equals 268411.19719 base units, and 1 slug per quart equals 15421.2051633 base units, so dividing one by the other gives the direct long ton per gallon-to-slug per quart factor of 17.4053320961.
Simple example
1 long ton/gal × 17.4053321 = 17.4053321 slug/qt
1 long ton per gallon = 17.4053321 slugs per quart.
Real-world example
1,000 long ton/gal × 17.4053321 = 17,405.3321 slug/qt
1,000 long tons per gallon = 17,405.3321 slugs per quart.

What is a long ton per gallon?
Long ton per Gallon (long ton/gal) is a unit of density.
What is a slug per quart?
Slug per Quart (slug/qt) is a unit of density.
Is the long ton per gallon to slug per quart conversion exact?
Yes. Both long ton per gallon and slug per quart are defined by fixed standards rather than physical artifacts, so the factor of 17.4053321 used above is exact to as many digits as you choose to display.
