About Converting Grams per Fluid ounce to Carats per Gallon
Gram per Fluid ounce and Carat 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
carats per gallon = grams per fluid ounce × 640
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 carat per gallon equals 0.0528344104716 base units, so dividing one by the other gives the direct gram per fluid ounce-to-carat per gallon factor of 640.
Simple example
1 g/fl oz × 640 = 640 ct/gal
1 gram per fluid ounce = 640 carats per gallon.
Real-world example
1,000 g/fl oz × 640 = 640,000 ct/gal
1,000 grams per fluid ounce = 640,000 carats per gallon.

Frequently asked questions
How many carats per gallon are in 1 gram per fluid ounce?
1 gram per fluid ounce equals 640 carats per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert gram per fluid ounce to carat per gallon?
Multiply the gram per fluid ounce value by 640. The converter above does this instantly to whatever precision you set.
How do I convert carat per gallon back to gram per fluid ounce?
Use the reverse factor: 1 carat per gallon equals 0.0015625 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 carat per gallon?
Carat per Gallon (ct/gal) is a unit of density.
Is the gram per fluid ounce to carat per gallon conversion exact?
Yes. Both gram per fluid ounce and carat per gallon are defined by fixed standards rather than physical artifacts, so the factor of 640 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.
