About Converting Carats per Cubic Meter to Pounds per Gallon
Carat per Cubic Meter and Pound 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
pounds per gallon = carats per cubic meter × 0.0000016690808904
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cubic meter equals 0.0002 base units, and 1 pound per gallon equals 119.826427317 base units, so dividing one by the other gives the direct carat per cubic meter-to-pound per gallon factor of 0.0000016690808904.
Simple example
1 ct/m3 × 0.00000166908089 = 0.0000016691 lb/gal
1 carat per cubic meter = 0.0000016691 pounds per gallon.
Real-world example
1,000 ct/m3 × 0.00000166908089 = 0.0016690809 lb/gal
1,000 carats per cubic meter = 0.0016690809 pounds per gallon.

Understanding the Carat per Cubic Meter (ct/m3)
Mass per volume density.
Understanding the Pound per Gallon
Pound per Gallon (lb/gal) measures density. The US customary unit for liquid density, based on the US gallon (231 cubic inches). It is classified as a US customary density unit.
Where it's used: United States (paint, fuel, and industrial liquid density specifications)
lb/gal vs. lb/ft³. Both are US customary density units; they're related through the real, fixed relationship between the US gallon and the cubic foot (1 cubic foot ≈ 7.48 US gallons), not a round conversion factor.
Uses of the Pound per Gallon today
- US paint and coatings density specifications
- US fuel and petroleum liquid density specs
- Industrial liquid handling and shipping weight calculations
