About Converting Ounces per Gallon to Decigrams per Teaspoon
Ounce per Gallon and Decigram 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. Ounce per Gallon is most often used for used to express dilution rates on many us pesticide, herbicide, and household cleaning product labels, which commonly specify a number of fluid ounces of concentrate per gallon of water.
Formula
decigrams per teaspoon = ounces per gallon × 0.36913441569
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per gallon equals 7.48915170731 base units, and 1 decigram per teaspoon equals 20.2884136211 base units, so dividing one by the other gives the direct ounce per gallon-to-decigram per teaspoon factor of 0.36913441569.
Simple example
1 oz/gal × 0.3691344157 = 0.3691344157 dg/tsp
1 ounce per gallon = 0.3691344157 decigrams per teaspoon.
Real-world example
1,000 oz/gal × 0.3691344157 = 369.1344157 dg/tsp
1,000 ounces per gallon = 369.1344157 decigrams per teaspoon.

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.
