About Converting Pounds per Cubic Centimeter to Centigrams per Gallon
Pound per Cubic Centimeter and Centigram 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
centigrams per gallon = pounds per cubic centimeter × 171703390.253
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic centimeter equals 453592.37 base units, and 1 centigram per gallon equals 0.00264172052358 base units, so dividing one by the other gives the direct pound per cubic centimeter-to-centigram per gallon factor of 171703390.253.
Simple example
1 lb/cm3 × 171703390.3 = 171,703,390.3 cg/gal
1 pound per cubic centimeter = 171,703,390.3 centigrams per gallon.
Real-world example
1,000 lb/cm3 × 171703390.3 = 171,703,390,300 cg/gal
1,000 pounds per cubic centimeter = 171,703,390,300 centigrams per gallon.

Frequently asked questions
How many centigrams per gallon are in 1 pound per cubic centimeter?
1 pound per cubic centimeter equals 171,703,390.3 centigrams per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert pound per cubic centimeter to centigram per gallon?
Multiply the pound per cubic centimeter value by 171703390.3. The converter above does this instantly to whatever precision you set.
How do I convert centigram per gallon back to pound per cubic centimeter?
Use the reverse factor: 1 centigram per gallon equals 5.823997e-9 pounds per cubic centimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a pound per cubic centimeter?
Pound per Cubic Centimeter (lb/cm3) is a unit of density.
What is a centigram per gallon?
Centigram per Gallon (cg/gal) is a unit of density.
Is the pound per cubic centimeter to centigram per gallon conversion exact?
Yes. Both pound per cubic centimeter and centigram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 171703390.3 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
