About Converting Ounces per Imperial gallon to Milligrams per Gallon
Ounce per Imperial 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 = ounces per imperial gallon × 23605.9160527
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per imperial gallon equals 6.23602329144 base units, and 1 milligram per gallon equals 0.000264172052358 base units, so dividing one by the other gives the direct ounce per imperial gallon-to-milligram per gallon factor of 23605.9160527.
Simple example
1 oz/imp gal × 23605.91605 = 23,605.91605 mg/gal
1 ounce per imperial gallon = 23,605.91605 milligrams per gallon.
Real-world example
1,000 oz/imp gal × 23605.91605 = 23,605,916.05 mg/gal
1,000 ounces per imperial gallon = 23,605,916.05 milligrams per gallon.

What is a ounce per imperial gallon?
Ounce per Imperial gallon (oz/imp gal) is a unit of density.
What is a milligram per gallon?
Milligram per Gallon (mg/gal) is a unit of density.
Is the ounce per imperial gallon to milligram per gallon conversion exact?
Yes. Both ounce per imperial gallon and milligram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 23605.91605 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.
