About Converting Pounds per Quart to Ounces per Gallon
Pound per Quart 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 = pounds per quart × 64
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per quart equals 479.305709268 base units, and 1 ounce per gallon equals 7.48915170731 base units, so dividing one by the other gives the direct pound per quart-to-ounce per gallon factor of 64.
Simple example
1 lb/qt × 64 = 64 oz/gal
1 pound per quart = 64 ounces per gallon.
Real-world example
1,000 lb/qt × 64 = 64,000 oz/gal
1,000 pounds per quart = 64,000 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 pound per quart?
1 pound per quart equals 64 ounces per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert pound per quart to ounce per gallon?
Multiply the pound per quart value by 64. The converter above does this instantly to whatever precision you set.
How do I convert ounce per gallon back to pound per quart?
Use the reverse factor: 1 ounce per gallon equals 0.015625 pounds per quart. You can also use the swap control in the converter above to flip the direction instantly.
What is a pound per quart?
Pound per Quart (lb/qt) 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 pound per quart to ounce per gallon conversion exact?
Yes. Both pound per quart and ounce per gallon are defined by fixed standards rather than physical artifacts, so the factor of 64 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.
