About Converting Milligrams per Milliliter to Ounces per Gallon
Milligram per Milliliter and Ounce 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
ounces per gallon = milligrams per milliliter × 0.133526471232
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per milliliter equals 1 base unit, and 1 ounce per gallon equals 7.48915170731 base units, so dividing one by the other gives the direct milligram per milliliter-to-ounce per gallon factor of 0.133526471232.
Simple example
1 mg/mL × 0.1335264712 = 0.1335264712 oz/gal
1 milligram per milliliter = 0.1335264712 ounces per gallon.
Real-world example
1,000 mg/mL × 0.1335264712 = 133.5264712 oz/gal
1,000 milligrams per milliliter = 133.5264712 ounces per gallon.

Understanding the Ounce per Gallon
Ounce per Gallon (oz/gal) measures concentration (dilution rate). A US customary way to express how much concentrate is mixed into each gallon of a diluted solution. It is classified as a US customary concentration unit.
Where it's used: United States
Uses of the Ounce per Gallon today
- 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
Ounce per Gallon — sources
- US product-label dilution conventions (pesticide/herbicide industry guides) — Fluid ounces of concentrate per gallon is a widely used label format for US spray and cleaning product dilution instructions.

Frequently asked questions
How many ounces per gallon are in 1 milligram per milliliter?
1 milligram per milliliter equals 0.1335264712 ounces per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert milligram per milliliter to ounce per gallon?
Multiply the milligram per milliliter value by 0.1335264712. The converter above does this instantly to whatever precision you set.
How do I convert ounce per gallon back to milligram per milliliter?
Use the reverse factor: 1 ounce per gallon equals 7.489151707 milligrams per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a milligram per milliliter?
Milligram per Milliliter (mg/mL) is a unit of density.
What is a ounce per gallon?
Ounce per Gallon (oz/gal) measures concentration (dilution rate). A US customary way to express how much concentrate is mixed into each gallon of a diluted solution. It is classified as a US customary concentration unit.
Is the milligram per milliliter to ounce per gallon conversion exact?
Yes. Both milligram per milliliter and ounce per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.1335264712 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.
