About Converting Drams per Fluid ounce to Ounces per Quart
Dram per Fluid ounce and Ounce 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
ounces per quart = drams per fluid ounce × 2
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per fluid ounce equals 59.9132136584 base units, and 1 ounce per quart equals 29.9566068292 base units, so dividing one by the other gives the direct dram per fluid ounce-to-ounce per quart factor of 2.
Simple example
1 dr/fl oz × 2 = 2 oz/qt
1 dram per fluid ounce = 2 ounces per quart.
Real-world example
1,000 dr/fl oz × 2 = 2,000 oz/qt
1,000 drams per fluid ounce = 2,000 ounces per quart.

Frequently asked questions
How many ounces per quart are in 1 dram per fluid ounce?
1 dram per fluid ounce equals 2 ounces per quart, using the exact defined conversion factor rather than an estimate.
How do I convert dram per fluid ounce to ounce per quart?
Multiply the dram per fluid ounce value by 2. The converter above does this instantly to whatever precision you set.
How do I convert ounce per quart back to dram per fluid ounce?
Use the reverse factor: 1 ounce per quart equals 0.5 drams per fluid ounce. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per fluid ounce?
Dram per Fluid ounce (dr/fl oz) is a unit of density.
What is a ounce per quart?
Ounce per Quart (oz/qt) is a unit of density.
Is the dram per fluid ounce to ounce per quart conversion exact?
Yes. Both dram per fluid ounce and ounce per quart are defined by fixed standards rather than physical artifacts, so the factor of 2 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.
