About Converting Drams per Gallon to Ounces per Teaspoon
Dram per Gallon and Ounce per Teaspoon 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 teaspoon = drams per gallon × 0.0000813802083333
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 teaspoon equals 5751.66851121 base units, so dividing one by the other gives the direct dram per gallon-to-ounce per teaspoon factor of 0.0000813802083333.
Simple example
1 dr/gal × 0.00008138020833 = 0.0000813802 oz/tsp
1 dram per gallon = 0.0000813802 ounces per teaspoon.
Real-world example
1,000 dr/gal × 0.00008138020833 = 0.0813802083 oz/tsp
1,000 drams per gallon = 0.0813802083 ounces per teaspoon.

What is a dram per gallon?
Dram per Gallon (dr/gal) is a unit of density.
What is a ounce per teaspoon?
Ounce per Teaspoon (oz/tsp) is a unit of density.
Is the dram per gallon to ounce per teaspoon conversion exact?
