About Converting Stones per Gallon to Long tons per Pint
Stone per Gallon and Long ton per Pint 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 pint = stones per gallon × 0.00078125
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per gallon equals 1677.56998244 base units, and 1 long ton per pint equals 2147289.57752 base units, so dividing one by the other gives the direct stone per gallon-to-long ton per pint factor of 0.00078125.
Simple example
1 st/gal × 0.00078125 = 0.00078125 long ton/pt
1 stone per gallon = 0.00078125 long tons per pint.
Real-world example
1,000 st/gal × 0.00078125 = 0.78125 long ton/pt
1,000 stones per gallon = 0.78125 long tons per pint.

Multiply the stone per gallon value by 0.00078125. The converter above does this instantly to whatever precision you set.
How do I convert long ton per pint back to stone per gallon?
Use the reverse factor: 1 long ton per pint equals 1,280 stones per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a stone per gallon?
Stone per Gallon (st/gal) is a unit of density.
What is a long ton per pint?
Long ton per Pint (long ton/pt) is a unit of density.
Is the stone per gallon to long ton per pint conversion exact?
Yes. Both stone per gallon and long ton per pint are defined by fixed standards rather than physical artifacts, so the factor of 0.00078125 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.
