About Converting Ounces per Liter to Grains per Gallon
Ounce per Liter and Grain 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
grains per gallon = ounces per liter × 1656.1176555
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per liter equals 28.349523125 base units, and 1 grain per gallon equals 0.0171180610453 base units, so dividing one by the other gives the direct ounce per liter-to-grain per gallon factor of 1656.1176555.
Simple example
1 oz/L × 1656.117656 = 1,656.117656 gr/gal
1 ounce per liter = 1,656.117656 grains per gallon.
Real-world example
1,000 oz/L × 1656.117656 = 1,656,117.656 gr/gal
1,000 ounces per liter = 1,656,117.656 grains per gallon.

Multiply the ounce per liter value by 1656.117656. The converter above does this instantly to whatever precision you set.
How do I convert grain per gallon back to ounce per liter?
Use the reverse factor: 1 grain per gallon equals 0.0006038218 ounces per liter. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per liter?
Ounce per Liter (oz/L) is a unit of density.
What is a grain per gallon?
Grain per Gallon (gr/gal) is a unit of density.
Is the ounce per liter to grain per gallon conversion exact?
Yes. Both ounce per liter and grain per gallon are defined by fixed standards rather than physical artifacts, so the factor of 1656.117656 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.
