About Converting Carats per Fluid ounce to Grains per Milliliter
Carat per Fluid ounce and Grain 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
grains per milliliter = carats per fluid ounce × 0.104366023138
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per fluid ounce equals 6.76280454037 base units, and 1 grain per milliliter equals 64.79891 base units, so dividing one by the other gives the direct carat per fluid ounce-to-grain per milliliter factor of 0.104366023138.
Simple example
1 ct/fl oz × 0.1043660231 = 0.1043660231 gr/mL
1 carat per fluid ounce = 0.1043660231 grains per milliliter.
Real-world example
1,000 ct/fl oz × 0.1043660231 = 104.3660231 gr/mL
1,000 carats per fluid ounce = 104.3660231 grains per milliliter.

Frequently asked questions
How many grains per milliliter are in 1 carat per fluid ounce?
1 carat per fluid ounce equals 0.1043660231 grains per milliliter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per fluid ounce to grain per milliliter?
Multiply the carat per fluid ounce value by 0.1043660231. The converter above does this instantly to whatever precision you set.
How do I convert grain per milliliter back to carat per fluid ounce?
Use the reverse factor: 1 grain per milliliter equals 9.581662403 carats per fluid ounce. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per fluid ounce?
Carat per Fluid ounce (ct/fl oz) is a unit of density.
What is a grain per milliliter?
Grain per Milliliter (gr/mL) is a unit of density.
Is the carat per fluid ounce to grain per milliliter conversion exact?
Yes. Both carat per fluid ounce and grain per milliliter are defined by fixed standards rather than physical artifacts, so the factor of 0.1043660231 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.
