About Converting Long tons per Gallon to Stones per Gallon
Long ton per Gallon and Stone 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
stones per gallon = long tons per gallon × 160
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 stone per gallon equals 1677.56998244 base units, so dividing one by the other gives the direct long ton per gallon-to-stone per gallon factor of 160.
Simple example
1 long ton/gal × 160 = 160 st/gal
1 long ton per gallon = 160 stones per gallon.
Real-world example
1,000 long ton/gal × 160 = 160,000 st/gal
1,000 long tons per gallon = 160,000 stones per gallon.

Frequently asked questions
How many stones per gallon are in 1 long ton per gallon?
1 long ton per gallon equals 160 stones per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert long ton per gallon to stone per gallon?
Multiply the long ton per gallon value by 160. The converter above does this instantly to whatever precision you set.
How do I convert stone per gallon back to long ton per gallon?
Use the reverse factor: 1 stone per gallon equals 0.00625 long tons per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a long ton per gallon?
Long ton per Gallon (long ton/gal) is a unit of density.
What is a stone per gallon?
Stone per Gallon (st/gal) is a unit of density.
Is the long ton per gallon to stone per gallon conversion exact?
Yes. Both long ton per gallon and stone per gallon are defined by fixed standards rather than physical artifacts, so the factor of 160 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.
