About Converting Ounces per Gallon to Milligrams per Tablespoon
Ounce per Gallon and Milligram 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
milligrams per tablespoon = ounces per gallon × 110.740324707
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 milligram per tablespoon equals 0.0676280454037 base units, so dividing one by the other gives the direct ounce per gallon-to-milligram per tablespoon factor of 110.740324707.
Simple example
1 oz/gal × 110.7403247 = 110.7403247 mg/tbsp
1 ounce per gallon = 110.7403247 milligrams per tablespoon.
Real-world example
1,000 oz/gal × 110.7403247 = 110,740.3247 mg/tbsp
1,000 ounces per gallon = 110,740.3247 milligrams 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.
