About Converting Ounces per Quart to Drams per Gallon
Ounce per Quart and Dram per Gallon 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 gallon = ounces per quart × 64
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per quart equals 29.9566068292 base units, and 1 dram per gallon equals 0.468071981707 base units, so dividing one by the other gives the direct ounce per quart-to-dram per gallon factor of 64.
Simple example
1 oz/qt × 64 = 64 dr/gal
1 ounce per quart = 64 drams per gallon.
Real-world example
1,000 oz/qt × 64 = 64,000 dr/gal
1,000 ounces per quart = 64,000 drams per gallon.

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