About Converting Pounds per Gallon to Ounces per Gallon
Pound per Gallon 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. Pound per Gallon is typically associated with united States (paint, fuel, and industrial liquid density specifications), while Ounce per Gallon is typically associated with united States.
Formula
ounces per gallon = pounds per gallon × 16
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per gallon equals 119.826427317 base units, and 1 ounce per gallon equals 7.48915170731 base units, so dividing one by the other gives the direct pound per gallon-to-ounce per gallon factor of 16.
Simple example
1 lb/gal × 16 = 16 oz/gal
1 pound per gallon = 16 ounces per gallon.
Real-world example
1,000 lb/gal × 16 = 16,000 oz/gal
1,000 pounds per gallon = 16,000 ounces per gallon.
Conversion table
| Pound per Gallon (lb/gal) | Ounce per Gallon (oz/gal) |
|---|---|
| 0.1 lb/gal | 1.6 oz/gal |
| 1 lb/gal | 16 oz/gal |
| 10 lb/gal | 160 oz/gal |
| 100 lb/gal | 1,600 oz/gal |
| 1,000 lb/gal | 16,000 oz/gal |
| 10,000 lb/gal | 160,000 oz/gal |
Reverse conversion: Ounce per Gallon to Pound per Gallon
16 oz/gal × 0.0625 = 1 lb/gal
16 ounces per gallon = 1 pound per gallon.
pounds per gallon = ounces per gallon × 0.0625

Pound per Gallon vs. Ounce per Gallon
| Aspect | Pound per Gallon | Ounce per Gallon |
|---|---|---|
| Family | US customary density unit | US customary concentration unit |
| Typical use | US paint and coatings density specifications | 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
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

Frequently asked questions
How many ounces per gallon are in 1 pound per gallon?
1 pound per gallon equals 16 ounces per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert pound per gallon to ounce per gallon?
Multiply the pound per gallon value by 16. The converter above does this instantly to whatever precision you set.
How do I convert ounce per gallon back to pound per gallon?
Use the reverse factor: 1 ounce per gallon equals 0.0625 pounds per gallon. You can also use the swap control in the converter above to flip the direction instantly.
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.
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 gallon to ounce per gallon conversion exact?
Yes. Both pound per gallon and ounce per gallon are defined by fixed standards rather than physical artifacts, so the factor of 16 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.
