About Converting Pounds per Cup to Short tons per Cubic Centimeter
Pound per Cup and Short ton per Cubic Centimeter 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
short tons per cubic centimeter = pounds per cup × 0.00000211337641887
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 short ton per cubic centimeter equals 907184740 base units, so dividing one by the other gives the direct pound per cup-to-short ton per cubic centimeter factor of 0.00000211337641887.
Simple example
1 lb/cup × 0.000002113376419 = 0.0000021134 ton/cm3
1 pound per cup = 0.0000021134 short tons per cubic centimeter.
Real-world example
1,000 lb/cup × 0.000002113376419 = 0.0021133764 ton/cm3
1,000 pounds per cup = 0.0021133764 short tons per cubic centimeter.
