About Converting US hundredweights per Cup to Pounds per Cubic Millimeter
US hundredweight per Cup 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 = us hundredweights per cup × 0.000422675283773
