About Converting Nanograms per Fluid ounce to Drams per Quart
Nanogram per Fluid ounce and Dram per Quart 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 quart = nanograms per fluid ounce × 1.806027e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 nanogram per fluid ounce equals 3.381402e-8 base units, and 1 dram per quart equals 1.87228792683 base units, so dividing one by the other gives the direct nanogram per fluid ounce-to-dram per quart factor of 1.806027e-8.
Simple example
1 ng/fl oz × 1.806027e-8 = 1.806027e-8 dr/qt
1 nanogram per fluid ounce = 1.806027e-8 drams per quart.
Real-world example
1,000 ng/fl oz × 1.806027e-8 = 0.0000180603 dr/qt
1,000 nanograms per fluid ounce = 0.0000180603 drams per quart.

Frequently asked questions
How many drams per quart are in 1 nanogram per fluid ounce?
1 nanogram per fluid ounce equals 1.806027e-8 drams per quart, using the exact defined conversion factor rather than an estimate.
How do I convert nanogram per fluid ounce to dram per quart?
Multiply the nanogram per fluid ounce value by 1.806027e-8. The converter above does this instantly to whatever precision you set.
How do I convert dram per quart back to nanogram per fluid ounce?
Use the reverse factor: 1 dram per quart equals 55,370,162.35 nanograms per fluid ounce. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanogram per fluid ounce?
Nanogram per Fluid ounce (ng/fl oz) is a unit of density.
What is a dram per quart?
Dram per Quart (dr/qt) is a unit of density.
Is the nanogram per fluid ounce to dram per quart conversion exact?
Yes. Both nanogram per fluid ounce and dram per quart are defined by fixed standards rather than physical artifacts, so the factor of 1.806027e-8 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.
