About Converting Stones per Gallon to Ounces per Cup
Stone per Gallon and Ounce per Cup 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
ounces per cup = stones per gallon × 14
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 ounce per cup equals 119.826427317 base units, so dividing one by the other gives the direct stone per gallon-to-ounce per cup factor of 14.
Simple example
1 st/gal × 14 = 14 oz/cup
1 stone per gallon = 14 ounces per cup.
Real-world example
1,000 st/gal × 14 = 14,000 oz/cup
1,000 stones per gallon = 14,000 ounces per cup.

Frequently asked questions
How many ounces per cup are in 1 stone per gallon?
1 stone per gallon equals 14 ounces per cup, using the exact defined conversion factor rather than an estimate.
How do I convert stone per gallon to ounce per cup?
Multiply the stone per gallon value by 14. The converter above does this instantly to whatever precision you set.
How do I convert ounce per cup back to stone per gallon?
Use the reverse factor: 1 ounce per cup equals 0.0714285714 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 ounce per cup?
Ounce per Cup (oz/cup) is a unit of density.
Is the stone per gallon to ounce per cup conversion exact?
Yes. Both stone per gallon and ounce per cup are defined by fixed standards rather than physical artifacts, so the factor of 14 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.
