About Converting Grams per Gallon to Carats per Milliliter
Gram per Gallon and Carat per Milliliter 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 milliliter = grams per gallon × 0.00132086026179
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per gallon equals 0.264172052358 base units, and 1 carat per milliliter equals 200 base units, so dividing one by the other gives the direct gram per gallon-to-carat per milliliter factor of 0.00132086026179.
Simple example
1 g/gal × 0.001320860262 = 0.0013208603 ct/mL
1 gram per gallon = 0.0013208603 carats per milliliter.
Real-world example
1,000 g/gal × 0.001320860262 = 1.320860262 ct/mL
1,000 grams per gallon = 1.320860262 carats per milliliter.

Frequently asked questions
How many carats per milliliter are in 1 gram per gallon?
1 gram per gallon equals 0.0013208603 carats per milliliter, using the exact defined conversion factor rather than an estimate.
How do I convert gram per gallon to carat per milliliter?
Multiply the gram per gallon value by 0.001320860262. The converter above does this instantly to whatever precision you set.
How do I convert carat per milliliter back to gram per gallon?
Use the reverse factor: 1 carat per milliliter equals 757.0823568 grams per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per gallon?
Gram per Gallon (g/gal) is a unit of density.
What is a carat per milliliter?
Carat per Milliliter (ct/mL) is a unit of density.
Is the gram per gallon to carat per milliliter conversion exact?
Yes. Both gram per gallon and carat per milliliter are defined by fixed standards rather than physical artifacts, so the factor of 0.001320860262 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.
