About Converting Carat per Cubic inches to Pounds per Imperial gallon
Carat per Cubic inch and Pound per Imperial 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
pounds per imperial gallon = carat per cubic inches × 0.122321031455
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cubic inch equals 12.2047488189 base units, and 1 pound per imperial gallon equals 99.7763726631 base units, so dividing one by the other gives the direct carat per cubic inch-to-pound per imperial gallon factor of 0.122321031455.
Simple example
1 ct/in3 × 0.1223210315 = 0.1223210315 lb/imp gal
1 carat per cubic inch = 0.1223210315 pounds per imperial gallon.
Real-world example
1,000 ct/in3 × 0.1223210315 = 122.3210315 lb/imp gal
1,000 carat per cubic inches = 122.3210315 pounds per imperial gallon.
