About Converting Ounces per Cubic yard to Dram per Cubic inches
Ounce per Cubic yard 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 cubic yard × 0.000342935528121
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per cubic yard equals 0.0370797763286 base units, and 1 dram per cubic inch equals 108.124627774 base units, so dividing one by the other gives the direct ounce per cubic yard-to-dram per cubic inch factor of 0.000342935528121.
