About Converting Short tons per Cubic foot to Pounds per Quart
Short ton per Cubic foot and Pound per Quart 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 quart = short tons per cubic foot × 66.8402777778
This factor comes from each unit's defined relationship to the category's base unit: 1 short ton per cubic foot equals 32036.9267479 base units, and 1 pound per quart equals 479.305709268 base units, so dividing one by the other gives the direct short ton per cubic foot-to-pound per quart factor of 66.8402777778.
