About Converting Ounces per Liter to Drams per Milliliter
Ounce per Liter 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 = ounces per liter × 0.016
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per liter equals 28.349523125 base units, and 1 dram per milliliter equals 1771.84519531 base units, so dividing one by the other gives the direct ounce per liter-to-dram per milliliter factor of 0.016.
Simple example
1 oz/L × 0.016 = 0.016 dr/mL
1 ounce per liter = 0.016 drams per milliliter.
Real-world example
1,000 oz/L × 0.016 = 16 dr/mL
1,000 ounces per liter = 16 drams per milliliter.

Frequently asked questions
How many drams per milliliter are in 1 ounce per liter?
1 ounce per liter equals 0.016 drams per milliliter, using the exact defined conversion factor rather than an estimate.
How do I convert ounce per liter to dram per milliliter?
Multiply the ounce per liter value by 0.016. The converter above does this instantly to whatever precision you set.
How do I convert dram per milliliter back to ounce per liter?
Use the reverse factor: 1 dram per milliliter equals 62.5 ounces per liter. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per liter?
Ounce per Liter (oz/L) is a unit of density.
What is a dram per milliliter?
Dram per Milliliter (dr/mL) is a unit of density.
Is the ounce per liter to dram per milliliter conversion exact?
Yes. Both ounce per liter and dram per milliliter are defined by fixed standards rather than physical artifacts, so the factor of 0.016 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.
