About Converting Grain per Cubic inches to Ounces per Gallon
Grain per Cubic inch 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 = grain per cubic inches × 0.528
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per cubic inch equals 3.95427210146 base units, and 1 ounce per gallon equals 7.48915170731 base units, so dividing one by the other gives the direct grain per cubic inch-to-ounce per gallon factor of 0.528.
Simple example
1 gr/in3 × 0.528 = 0.528 oz/gal
1 grain per cubic inch = 0.528 ounces per gallon.
Real-world example
1,000 gr/in3 × 0.528 = 528 oz/gal
1,000 grain per cubic inches = 528 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 grain per cubic inch?
1 grain per cubic inch equals 0.528 ounces per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert grain per cubic inch to ounce per gallon?
Multiply the grain per cubic inch value by 0.528. The converter above does this instantly to whatever precision you set.
How do I convert ounce per gallon back to grain per cubic inch?
Use the reverse factor: 1 ounce per gallon equals 1.893939394 grain per cubic inches. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per cubic inch?
Grain per Cubic inch (gr/in3) 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 grain per cubic inch to ounce per gallon conversion exact?
Yes. Both grain per cubic inch and ounce per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.528 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.
