About Converting Long tons per Oil barrel to Pounds per Quart
Long ton per Oil barrel 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 = long tons per oil barrel × 13.3333333333
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per oil barrel equals 6390.74279023 base units, and 1 pound per quart equals 479.305709268 base units, so dividing one by the other gives the direct long ton per oil barrel-to-pound per quart factor of 13.3333333333.
Simple example
1 long ton/bbl × 13.33333333 = 13.33333333 lb/qt
1 long ton per oil barrel = 13.33333333 pounds per quart.
Real-world example
1,000 long ton/bbl × 13.33333333 = 13,333.33333 lb/qt
1,000 long tons per oil barrel = 13,333.33333 pounds per quart.
