About Converting Ounce per Cubic inches to Drams per Fluid ounce
Ounce per Cubic inch and Dram per Fluid ounce 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
drams per fluid ounce = ounce per cubic inches × 28.875
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 dram per fluid ounce equals 59.9132136584 base units, so dividing one by the other gives the direct ounce per cubic inch-to-dram per fluid ounce factor of 28.875.
Simple example
1 oz/in3 × 28.875 = 28.875 dr/fl oz
1 ounce per cubic inch = 28.875 drams per fluid ounce.
Real-world example
1,000 oz/in3 × 28.875 = 28,875 dr/fl oz
1,000 ounce per cubic inches = 28,875 drams per fluid ounce.

How do I convert dram per fluid ounce back to ounce per cubic inch?
Use the reverse factor: 1 dram per fluid ounce equals 0.0346320346 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 dram per fluid ounce?
Dram per Fluid ounce (dr/fl oz) is a unit of density.
Is the ounce per cubic inch to dram per fluid ounce conversion exact?
Yes. Both ounce per cubic inch and dram per fluid ounce are defined by fixed standards rather than physical artifacts, so the factor of 28.875 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.
