About Converting Ounces per Gallon to Ounces per Tablespoon
Ounce per Gallon and Ounce per Tablespoon 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
ounces per tablespoon = ounces per gallon × 0.00390625
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 ounce per tablespoon equals 1917.22283707 base units, so dividing one by the other gives the direct ounce per gallon-to-ounce per tablespoon factor of 0.00390625.
Simple example
1 oz/gal × 0.00390625 = 0.00390625 oz/tbsp
1 ounce per gallon = 0.00390625 ounces per tablespoon.
Real-world example
1,000 oz/gal × 0.00390625 = 3.90625 oz/tbsp
1,000 ounces per gallon = 3.90625 ounces per tablespoon.

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.
