About Converting Ounces per Milliliter to Drams per Liter
Ounce per Milliliter and Dram per Liter 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 liter = ounces per milliliter × 16000
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per milliliter equals 28349.523125 base units, and 1 dram per liter equals 1.77184519531 base units, so dividing one by the other gives the direct ounce per milliliter-to-dram per liter factor of 16000.
Simple example
1 oz/mL × 16000 = 16,000 dr/L
1 ounce per milliliter = 16,000 drams per liter.
Real-world example
1,000 oz/mL × 16000 = 16,000,000 dr/L
1,000 ounces per milliliter = 16,000,000 drams per liter.

Frequently asked questions
How many drams per liter are in 1 ounce per milliliter?
1 ounce per milliliter equals 16,000 drams per liter, using the exact defined conversion factor rather than an estimate.
How do I convert ounce per milliliter to dram per liter?
Multiply the ounce per milliliter value by 16000. The converter above does this instantly to whatever precision you set.
How do I convert dram per liter back to ounce per milliliter?
Use the reverse factor: 1 dram per liter equals 0.0000625 ounces per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per milliliter?
Ounce per Milliliter (oz/mL) is a unit of density.
What is a dram per liter?
Dram per Liter (dr/L) is a unit of density.
Is the ounce per milliliter to dram per liter conversion exact?
Yes. Both ounce per milliliter and dram per liter are defined by fixed standards rather than physical artifacts, so the factor of 16000 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.
