About Converting Stones per Gallon to Stones per Pint
Stone per Gallon and Stone 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
stones per pint = stones per gallon × 0.125
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 stone per pint equals 13420.5598595 base units, so dividing one by the other gives the direct stone per gallon-to-stone per pint factor of 0.125.
Simple example
1 st/gal × 0.125 = 0.125 st/pt
1 stone per gallon = 0.125 stones per pint.
Real-world example
1,000 st/gal × 0.125 = 125 st/pt
1,000 stones per gallon = 125 stones per pint.

Frequently asked questions
How many stones per pint are in 1 stone per gallon?
1 stone per gallon equals 0.125 stones per pint, using the exact defined conversion factor rather than an estimate.
How do I convert stone per gallon to stone per pint?
Multiply the stone per gallon value by 0.125. The converter above does this instantly to whatever precision you set.
How do I convert stone per pint back to stone per gallon?
Use the reverse factor: 1 stone per pint equals 8 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 stone per pint?
Stone per Pint (st/pt) is a unit of density.
Is the stone per gallon to stone per pint conversion exact?
Yes. Both stone per gallon and stone per pint are defined by fixed standards rather than physical artifacts, so the factor of 0.125 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.
