About Converting Pounds per Cubic yard to Short tons per Teaspoon
Pound per Cubic yard and Short ton per Teaspoon 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 teaspoon = pounds per cubic yard × 3.223393e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic yard equals 0.593276421258 base units, and 1 short ton per teaspoon equals 184053392.359 base units, so dividing one by the other gives the direct pound per cubic yard-to-short ton per teaspoon factor of 3.223393e-9.
