About Converting Grams per Imperial gallon to Centigrams per Liter
Gram per Imperial gallon and Centigram per Liter 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 liter = grams per imperial gallon × 21.9969248299
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per imperial gallon equals 0.219969248299 base units, and 1 centigram per liter equals 0.01 base units, so dividing one by the other gives the direct gram per imperial gallon-to-centigram per liter factor of 21.9969248299.
Simple example
1 g/imp gal × 21.99692483 = 21.99692483 cg/L
1 gram per imperial gallon = 21.99692483 centigrams per liter.
Real-world example
1,000 g/imp gal × 21.99692483 = 21,996.92483 cg/L
1,000 grams per imperial gallon = 21,996.92483 centigrams per liter.

Multiply the gram per imperial gallon value by 21.99692483. The converter above does this instantly to whatever precision you set.
How do I convert centigram per liter back to gram per imperial gallon?
Use the reverse factor: 1 centigram per liter equals 0.0454609 grams per imperial gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per imperial gallon?
Gram per Imperial gallon (g/imp gal) is a unit of density.
What is a centigram per liter?
Centigram per Liter (cg/L) is a unit of density.
Is the gram per imperial gallon to centigram per liter conversion exact?
Yes. Both gram per imperial gallon and centigram per liter are defined by fixed standards rather than physical artifacts, so the factor of 21.99692483 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.
