About Converting Ounces per Tablespoon to Dram per Cubic inches
Ounce per Tablespoon and Dram 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
dram per cubic inches = ounces per tablespoon × 17.7316017316
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per tablespoon equals 1917.22283707 base units, and 1 dram per cubic inch equals 108.124627774 base units, so dividing one by the other gives the direct ounce per tablespoon-to-dram per cubic inch factor of 17.7316017316.
