About Converting Carats per Pint to Long tons per Gallon
Carat per Pint and Long ton per Gallon 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 gallon = carats per pint × 0.00000157473044418
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per pint equals 0.422675283773 base units, and 1 long ton per gallon equals 268411.19719 base units, so dividing one by the other gives the direct carat per pint-to-long ton per gallon factor of 0.00000157473044418.
Simple example
1 ct/pt × 0.000001574730444 = 0.0000015747 long ton/gal
1 carat per pint = 0.0000015747 long tons per gallon.
Real-world example
1,000 ct/pt × 0.000001574730444 = 0.0015747304 long ton/gal
1,000 carats per pint = 0.0015747304 long tons per gallon.
