About Converting Slugs per Imperial gallon to Long tons per Gallon
Slug per Imperial gallon and Long ton 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
long tons per gallon = slugs per imperial gallon × 0.0119600444857
This factor comes from each unit's defined relationship to the category's base unit: 1 slug per imperial gallon equals 3210.20985885 base units, and 1 long ton per gallon equals 268411.19719 base units, so dividing one by the other gives the direct slug per imperial gallon-to-long ton per gallon factor of 0.0119600444857.
Simple example
1 slug/imp gal × 0.01196004449 = 0.0119600445 long ton/gal
1 slug per imperial gallon = 0.0119600445 long tons per gallon.
Real-world example
1,000 slug/imp gal × 0.01196004449 = 11.96004449 long ton/gal
1,000 slugs per imperial gallon = 11.96004449 long tons per gallon.
