About Converting Ounces per Teaspoon to Drams per Gallon
Ounce per Teaspoon 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 teaspoon × 12288
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per teaspoon equals 5751.66851121 base units, and 1 dram per gallon equals 0.468071981707 base units, so dividing one by the other gives the direct ounce per teaspoon-to-dram per gallon factor of 12288.
Simple example
1 oz/tsp × 12288 = 12,288 dr/gal
1 ounce per teaspoon = 12,288 drams per gallon.
Real-world example
1,000 oz/tsp × 12288 = 12,288,000 dr/gal
1,000 ounces per teaspoon = 12,288,000 drams per gallon.

Frequently asked questions
How many drams per gallon are in 1 ounce per teaspoon?
1 ounce per teaspoon equals 12,288 drams per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert ounce per teaspoon to dram per gallon?
Multiply the ounce per teaspoon value by 12288. The converter above does this instantly to whatever precision you set.
How do I convert dram per gallon back to ounce per teaspoon?
Use the reverse factor: 1 dram per gallon equals 0.0000813802 ounces per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per teaspoon?
Ounce per Teaspoon (oz/tsp) 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 teaspoon to dram per gallon conversion exact?
Yes. Both ounce per teaspoon and dram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 12288 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.
