About Converting Carats per Fluid ounce to Drams per Milliliter
Carat per Fluid ounce and Dram 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
drams per milliliter = carats per fluid ounce × 0.00381681456047
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 dram per milliliter equals 1771.84519531 base units, so dividing one by the other gives the direct carat per fluid ounce-to-dram per milliliter factor of 0.00381681456047.
Simple example
1 ct/fl oz × 0.00381681456 = 0.0038168146 dr/mL
1 carat per fluid ounce = 0.0038168146 drams per milliliter.
Real-world example
1,000 ct/fl oz × 0.00381681456 = 3.81681456 dr/mL
1,000 carats per fluid ounce = 3.81681456 drams per milliliter.

Frequently asked questions
How many drams per milliliter are in 1 carat per fluid ounce?
1 carat per fluid ounce equals 0.0038168146 drams per milliliter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per fluid ounce to dram per milliliter?
Multiply the carat per fluid ounce value by 0.00381681456. The converter above does this instantly to whatever precision you set.
How do I convert dram per milliliter back to carat per fluid ounce?
Use the reverse factor: 1 dram per milliliter equals 261.9985813 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 dram per milliliter?
Dram per Milliliter (dr/mL) is a unit of density.
Is the carat per fluid ounce to dram per milliliter conversion exact?
Yes. Both carat per fluid ounce and dram per milliliter are defined by fixed standards rather than physical artifacts, so the factor of 0.00381681456 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.
