About Converting Pounds per Cubic Meter to Centigrams per Gallon
Pound per Cubic Meter 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 meter × 171.703390253
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic meter equals 0.45359237 base units, and 1 centigram per gallon equals 0.00264172052358 base units, so dividing one by the other gives the direct pound per cubic meter-to-centigram per gallon factor of 171.703390253.
Simple example
1 lb/m3 × 171.7033903 = 171.7033903 cg/gal
1 pound per cubic meter = 171.7033903 centigrams per gallon.
Real-world example
1,000 lb/m3 × 171.7033903 = 171,703.3903 cg/gal
1,000 pounds per cubic meter = 171,703.3903 centigrams per gallon.

Frequently asked questions
How many centigrams per gallon are in 1 pound per cubic meter?
1 pound per cubic meter equals 171.7033903 centigrams per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert pound per cubic meter to centigram per gallon?
Multiply the pound per cubic meter value by 171.7033903. The converter above does this instantly to whatever precision you set.
How do I convert centigram per gallon back to pound per cubic meter?
Use the reverse factor: 1 centigram per gallon equals 0.0058239968 pounds per cubic meter. You can also use the swap control in the converter above to flip the direction instantly.
What is a pound per cubic meter?
Pound per Cubic Meter (lb/m3) 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 meter to centigram per gallon conversion exact?
Yes. Both pound per cubic meter and centigram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 171.7033903 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.
