About Converting Ounces per Gallon to Pounds per Gallon
Ounce per Gallon and Pound per Gallon both measure mass concentration — how much of a substance is dissolved or dispersed in a given volume — a core calculation for preparing lab solutions, checking water quality against a regulatory limit, or formulating a pharmaceutical dose. Ounce per Gallon is typically associated with united States, while Pound per Gallon is typically associated with united States (paint, fuel, and industrial liquid density specifications).
Formula
pounds per gallon = ounces per gallon × 0.0625
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per gallon equals 7.48915170731 base units, and 1 pound per gallon equals 119.826427317 base units, so dividing one by the other gives the direct ounce per gallon-to-pound per gallon factor of 0.0625.
Simple example
1 oz/gal × 0.0625 = 0.0625 lb/gal
1 ounce per gallon = 0.0625 pounds per gallon.
Real-world example
100 oz/gal × 0.0625 = 6.25 lb/gal
100 ounces per gallon = 6.25 pounds per gallon.

Ounce per Gallon vs. Pound per Gallon
| Aspect | Ounce per Gallon | Pound per Gallon |
|---|---|---|
| Family | US customary concentration unit | US customary density unit |
| Typical use | 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 | US paint and coatings density specifications |
| Where it's used | United States | United States (paint, fuel, and industrial liquid density specifications) |
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
Understanding the Pound per Gallon
Pound per Gallon (lb/gal) measures density. The US customary unit for liquid density, based on the US gallon (231 cubic inches). It is classified as a US customary density unit.
Where it's used: United States (paint, fuel, and industrial liquid density specifications)
lb/gal vs. lb/ft³. Both are US customary density units; they're related through the real, fixed relationship between the US gallon and the cubic foot (1 cubic foot ≈ 7.48 US gallons), not a round conversion factor.
Uses of the Pound per Gallon today
- US paint and coatings density specifications
- US fuel and petroleum liquid density specs
- Industrial liquid handling and shipping weight calculations

Use the reverse factor: 1 pound per gallon equals 16 ounces per gallon. You can also use the swap control in the converter above to flip the direction instantly.
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.
What is a pound per gallon?
Pound per Gallon (lb/gal) measures density. The US customary unit for liquid density, based on the US gallon (231 cubic inches). It is classified as a US customary density unit.
Is the ounce per gallon to pound per gallon conversion exact?
Yes. Both ounce per gallon and pound per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.0625 used above is exact to as many digits as you choose to display.
What is the difference between lb/gal vs. lb/ft³?
Both are US customary density units; they're related through the real, fixed relationship between the US gallon and the cubic foot (1 cubic foot ≈ 7.48 US gallons), not a round conversion factor.
