About Converting Centigrams per Imperial gallon to Milligrams per Gallon
Centigram per Imperial gallon and Milligram 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
milligrams per gallon = centigrams per imperial gallon × 8.32674184629
This factor comes from each unit's defined relationship to the category's base unit: 1 centigram per imperial gallon equals 0.00219969248299 base units, and 1 milligram per gallon equals 0.000264172052358 base units, so dividing one by the other gives the direct centigram per imperial gallon-to-milligram per gallon factor of 8.32674184629.
Simple example
1 cg/imp gal × 8.326741846 = 8.326741846 mg/gal
1 centigram per imperial gallon = 8.326741846 milligrams per gallon.
Real-world example
1,000 cg/imp gal × 8.326741846 = 8,326.741846 mg/gal
1,000 centigrams per imperial gallon = 8,326.741846 milligrams per gallon.

Multiply the centigram per imperial gallon value by 8.326741846. The converter above does this instantly to whatever precision you set.
How do I convert milligram per gallon back to centigram per imperial gallon?
Use the reverse factor: 1 milligram per gallon equals 0.1200949926 centigrams per imperial gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a centigram per imperial gallon?
Centigram per Imperial gallon (cg/imp gal) is a unit of density.
What is a milligram per gallon?
Milligram per Gallon (mg/gal) is a unit of density.
Is the centigram per imperial gallon to milligram per gallon conversion exact?
Yes. Both centigram per imperial gallon and milligram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 8.326741846 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.
