About Converting Ounces per Cubic yard to Long tons per Quart
Ounce per Cubic yard and Long ton 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
long tons per quart = ounces per cubic yard × 3.453635e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per cubic yard equals 0.0370797763286 base units, and 1 long ton per quart equals 1073644.78876 base units, so dividing one by the other gives the direct ounce per cubic yard-to-long ton per quart factor of 3.453635e-8.
Simple example
1 oz/yd3 × 3.453635e-8 = 3.453635e-8 long ton/qt
1 ounce per cubic yard = 3.453635e-8 long tons per quart.
Real-world example
1,000 oz/yd3 × 3.453635e-8 = 0.0000345364 long ton/qt
1,000 ounces per cubic yard = 0.0000345364 long tons per quart.
