About Converting Dram per Cubic inches to Ounces per Teaspoon
Dram per Cubic inch and Ounce per Teaspoon 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 teaspoon = dram per cubic inches × 0.018798828125
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per cubic inch equals 108.124627774 base units, and 1 ounce per teaspoon equals 5751.66851121 base units, so dividing one by the other gives the direct dram per cubic inch-to-ounce per teaspoon factor of 0.018798828125.
Simple example
1 dr/in3 × 0.01879882813 = 0.0187988281 oz/tsp
1 dram per cubic inch = 0.0187988281 ounces per teaspoon.
Real-world example
1,000 dr/in3 × 0.01879882813 = 18.79882813 oz/tsp
1,000 dram per cubic inches = 18.79882813 ounces per teaspoon.
