About Converting Ounces per Pint to Drams per Liter
Ounce per Pint 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 pint × 33.8140227018
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per pint equals 59.9132136584 base units, and 1 dram per liter equals 1.77184519531 base units, so dividing one by the other gives the direct ounce per pint-to-dram per liter factor of 33.8140227018.
Simple example
1 oz/pt × 33.8140227 = 33.8140227 dr/L
1 ounce per pint = 33.8140227 drams per liter.
Real-world example
1,000 oz/pt × 33.8140227 = 33,814.0227 dr/L
1,000 ounces per pint = 33,814.0227 drams per liter.

What is a ounce per pint?
Ounce per Pint (oz/pt) 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 pint to dram per liter conversion exact?
Yes. Both ounce per pint and dram per liter are defined by fixed standards rather than physical artifacts, so the factor of 33.8140227 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.
