About Converting Ounces per Milliliter to Milligrams per Gallon
Ounce per Milliliter 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 milliliter × 107314618.908
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per milliliter equals 28349.523125 base units, and 1 milligram per gallon equals 0.000264172052358 base units, so dividing one by the other gives the direct ounce per milliliter-to-milligram per gallon factor of 107314618.908.
Simple example
1 oz/mL × 107314618.9 = 107,314,618.9 mg/gal
1 ounce per milliliter = 107,314,618.9 milligrams per gallon.
Real-world example
1,000 oz/mL × 107314618.9 = 107,314,618,900 mg/gal
1,000 ounces per milliliter = 107,314,618,900 milligrams per gallon.

Frequently asked questions
How many milligrams per gallon are in 1 ounce per milliliter?
1 ounce per milliliter equals 107,314,618.9 milligrams per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert ounce per milliliter to milligram per gallon?
Multiply the ounce per milliliter value by 107314618.9. The converter above does this instantly to whatever precision you set.
How do I convert milligram per gallon back to ounce per milliliter?
Use the reverse factor: 1 milligram per gallon equals 9.318395e-9 ounces per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per milliliter?
Ounce per Milliliter (oz/mL) 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 milliliter to milligram per gallon conversion exact?
Yes. Both ounce per milliliter and milligram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 107314618.9 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.
