About Converting Stone per Cubic inches to Ounces per Cubic foot
Stone per Cubic inch and Ounce per Cubic foot 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 cubic foot = stone per cubic inches × 387072
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per cubic inch equals 387518.665943 base units, and 1 ounce per cubic foot equals 1.00115396087 base units, so dividing one by the other gives the direct stone per cubic inch-to-ounce per cubic foot factor of 387072.
Simple example
1 st/in3 × 387072 = 387,072 oz/ft3
1 stone per cubic inch = 387,072 ounces per cubic foot.
Real-world example
1,000 st/in3 × 387072 = 387,072,000 oz/ft3
1,000 stone per cubic inches = 387,072,000 ounces per cubic foot.

How do I convert ounce per cubic foot back to stone per cubic inch?
Use the reverse factor: 1 ounce per cubic foot equals 0.0000025835 stone per cubic inches. You can also use the swap control in the converter above to flip the direction instantly.
What is a stone per cubic inch?
Stone per Cubic inch (st/in3) is a unit of density.
What is a ounce per cubic foot?
Ounce per Cubic foot (oz/ft3) is a unit of density.
Is the stone per cubic inch to ounce per cubic foot conversion exact?
Yes. Both stone per cubic inch and ounce per cubic foot are defined by fixed standards rather than physical artifacts, so the factor of 387072 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.
