About Converting Drams per Milliliter to Ounces per Liter
Dram per Milliliter and Ounce 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
ounces per liter = drams per milliliter × 62.5
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per milliliter equals 1771.84519531 base units, and 1 ounce per liter equals 28.349523125 base units, so dividing one by the other gives the direct dram per milliliter-to-ounce per liter factor of 62.5.
Simple example
1 dr/mL × 62.5 = 62.5 oz/L
1 dram per milliliter = 62.5 ounces per liter.
Real-world example
1,000 dr/mL × 62.5 = 62,500 oz/L
1,000 drams per milliliter = 62,500 ounces per liter.

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