About Converting Drams per Gallon to Ounces per Quart
Dram per Gallon 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 gallon × 0.015625
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per gallon equals 0.468071981707 base units, and 1 ounce per quart equals 29.9566068292 base units, so dividing one by the other gives the direct dram per gallon-to-ounce per quart factor of 0.015625.
Simple example
1 dr/gal × 0.015625 = 0.015625 oz/qt
1 dram per gallon = 0.015625 ounces per quart.
Real-world example
1,000 dr/gal × 0.015625 = 15.625 oz/qt
1,000 drams per gallon = 15.625 ounces per quart.

Frequently asked questions
How many ounces per quart are in 1 dram per gallon?
1 dram per gallon equals 0.015625 ounces per quart, using the exact defined conversion factor rather than an estimate.
How do I convert dram per gallon to ounce per quart?
Multiply the dram per gallon value by 0.015625. The converter above does this instantly to whatever precision you set.
How do I convert ounce per quart back to dram per gallon?
Use the reverse factor: 1 ounce per quart equals 64 drams per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per gallon?
Dram per Gallon (dr/gal) 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 gallon to ounce per quart conversion exact?
Yes. Both dram per gallon and ounce per quart are defined by fixed standards rather than physical artifacts, so the factor of 0.015625 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.
