About Converting Troy ounces per Gallon to Milligrams per Gallon
Troy ounce per Gallon and Milligram 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
milligrams per gallon = troy ounces per gallon × 31103.4768
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per gallon equals 8.21666930173 base units, and 1 milligram per gallon equals 0.000264172052358 base units, so dividing one by the other gives the direct troy ounce per gallon-to-milligram per gallon factor of 31103.4768.
Simple example
1 oz t/gal × 31103.4768 = 31,103.4768 mg/gal
1 troy ounce per gallon = 31,103.4768 milligrams per gallon.
Real-world example
1,000 oz t/gal × 31103.4768 = 31,103,476.8 mg/gal
1,000 troy ounces per gallon = 31,103,476.8 milligrams per gallon.

What is a troy ounce per gallon?
Troy ounce per Gallon (oz t/gal) is a unit of density.
What is a milligram per gallon?
Milligram per Gallon (mg/gal) is a unit of density.
Is the troy ounce per gallon to milligram per gallon conversion exact?
Yes. Both troy ounce per gallon and milligram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 31103.4768 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.
