About Converting Ounce per Cubic inches to Long tons per Cubic yard
Ounce per Cubic inch and Long ton per Cubic yard 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
long tons per cubic yard = ounce per cubic inches × 1.30178571429
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per cubic inch equals 1729.99404439 base units, and 1 long ton per cubic yard equals 1328.93918362 base units, so dividing one by the other gives the direct ounce per cubic inch-to-long ton per cubic yard factor of 1.30178571429.
