About Converting Ounce per Cubic inches to Stones per Gallon
Ounce per Cubic inch 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 = ounce per cubic inches × 1.03125
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per cubic inch equals 1729.99404439 base units, and 1 stone per gallon equals 1677.56998244 base units, so dividing one by the other gives the direct ounce per cubic inch-to-stone per gallon factor of 1.03125.
Simple example
1 oz/in3 × 1.03125 = 1.03125 st/gal
1 ounce per cubic inch = 1.03125 stones per gallon.
Real-world example
1,000 oz/in3 × 1.03125 = 1,031.25 st/gal
1,000 ounce per cubic inches = 1,031.25 stones per gallon.

How do I convert stone per gallon back to ounce per cubic inch?
Use the reverse factor: 1 stone per gallon equals 0.9696969697 ounce per cubic inches. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per cubic inch?
Ounce per Cubic inch (oz/in3) is a unit of density.
What is a stone per gallon?
Stone per Gallon (st/gal) is a unit of density.
Is the ounce per cubic inch to stone per gallon conversion exact?
Yes. Both ounce per cubic inch and stone per gallon are defined by fixed standards rather than physical artifacts, so the factor of 1.03125 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.
