About Converting Drams per Teaspoon to Ounce per Cubic inches
Dram per Teaspoon and Ounce per Cubic inch 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
ounce per cubic inches = drams per teaspoon × 0.207792207792
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per teaspoon equals 359.479281951 base units, and 1 ounce per cubic inch equals 1729.99404439 base units, so dividing one by the other gives the direct dram per teaspoon-to-ounce per cubic inch factor of 0.207792207792.
Simple example
1 dr/tsp × 0.2077922078 = 0.2077922078 oz/in3
1 dram per teaspoon = 0.2077922078 ounce per cubic inches.
Real-world example
1,000 dr/tsp × 0.2077922078 = 207.7922078 oz/in3
1,000 drams per teaspoon = 207.7922078 ounce per cubic inches.

What is a dram per teaspoon?
Dram per Teaspoon (dr/tsp) is a unit of density.
What is a ounce per cubic inch?
Ounce per Cubic inch (oz/in3) is a unit of density.
Is the dram per teaspoon to ounce per cubic inch conversion exact?
Yes. Both dram per teaspoon and ounce per cubic inch are defined by fixed standards rather than physical artifacts, so the factor of 0.2077922078 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.
