About Converting Pounds per Cup to Troy ounces per Cubic Millimeter
Pound per Cup and Troy ounce 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
troy ounces per cubic millimeter = pounds per cup × 0.0000616401455502
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cup equals 1917.22283707 base units, and 1 troy ounce per cubic millimeter equals 31103476.8 base units, so dividing one by the other gives the direct pound per cup-to-troy ounce per cubic millimeter factor of 0.0000616401455502.
Simple example
1 lb/cup × 0.00006164014555 = 0.0000616401 oz t/mm3
1 pound per cup = 0.0000616401 troy ounces per cubic millimeter.
Real-world example
1,000 lb/cup × 0.00006164014555 = 0.0616401456 oz t/mm3
1,000 pounds per cup = 0.0616401456 troy ounces per cubic millimeter.
