About Converting Grams per Fluid ounce to Centigrams per Gallon
Gram per Fluid ounce 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 = grams per fluid ounce × 12800
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per fluid ounce equals 33.8140227018 base units, and 1 centigram per gallon equals 0.00264172052358 base units, so dividing one by the other gives the direct gram per fluid ounce-to-centigram per gallon factor of 12800.
Simple example
1 g/fl oz × 12800 = 12,800 cg/gal
1 gram per fluid ounce = 12,800 centigrams per gallon.
Real-world example
1,000 g/fl oz × 12800 = 12,800,000 cg/gal
1,000 grams per fluid ounce = 12,800,000 centigrams per gallon.

Frequently asked questions
How many centigrams per gallon are in 1 gram per fluid ounce?
1 gram per fluid ounce equals 12,800 centigrams per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert gram per fluid ounce to centigram per gallon?
Multiply the gram per fluid ounce value by 12800. The converter above does this instantly to whatever precision you set.
How do I convert centigram per gallon back to gram per fluid ounce?
Use the reverse factor: 1 centigram per gallon equals 0.000078125 grams per fluid ounce. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per fluid ounce?
Gram per Fluid ounce (g/fl oz) is a unit of density.
What is a centigram per gallon?
Centigram per Gallon (cg/gal) is a unit of density.
Is the gram per fluid ounce to centigram per gallon conversion exact?
Yes. Both gram per fluid ounce and centigram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 12800 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.
