About Converting Picograms per Fluid ounce to Drams per Liter
Picogram per Fluid ounce 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 = picograms per fluid ounce × 1.908407e-11
This factor comes from each unit's defined relationship to the category's base unit: 1 picogram per fluid ounce equals 3.381402e-11 base units, and 1 dram per liter equals 1.77184519531 base units, so dividing one by the other gives the direct picogram per fluid ounce-to-dram per liter factor of 1.908407e-11.
Simple example
1 pg/fl oz × 1.908407e-11 = 1.908407e-11 dr/L
1 picogram per fluid ounce = 1.908407e-11 drams per liter.
Real-world example
1,000 pg/fl oz × 1.908407e-11 = 1.908407e-8 dr/L
1,000 picograms per fluid ounce = 1.908407e-8 drams per liter.

What is a picogram per fluid ounce?
Picogram per Fluid ounce (pg/fl oz) is a unit of density.
What is a dram per liter?
Dram per Liter (dr/L) is a unit of density.
Is the picogram per fluid ounce to dram per liter conversion exact?
Yes. Both picogram per fluid ounce and dram per liter are defined by fixed standards rather than physical artifacts, so the factor of 1.908407e-11 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.
