About Converting Troy ounces per Teaspoon to Pounds per Cubic Millimeter
Troy ounce per Teaspoon and Pound per Cubic Millimeter 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
pounds per cubic millimeter = troy ounces per teaspoon × 0.0000139120550545
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per teaspoon equals 6310.40202373 base units, and 1 pound per cubic millimeter equals 453592370 base units, so dividing one by the other gives the direct troy ounce per teaspoon-to-pound per cubic millimeter factor of 0.0000139120550545.
Simple example
1 oz t/tsp × 0.00001391205505 = 0.0000139121 lb/mm3
1 troy ounce per teaspoon = 0.0000139121 pounds per cubic millimeter.
Real-world example
1,000 oz t/tsp × 0.00001391205505 = 0.0139120551 lb/mm3
1,000 troy ounces per teaspoon = 0.0139120551 pounds per cubic millimeter.
