About Converting Grains per Liter to Stones per Gallon
Grain per Liter and Stone 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
stones per gallon = grains per liter × 0.0000386266508571
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per liter equals 0.06479891 base units, and 1 stone per gallon equals 1677.56998244 base units, so dividing one by the other gives the direct grain per liter-to-stone per gallon factor of 0.0000386266508571.
Simple example
1 gr/L × 0.00003862665086 = 0.0000386267 st/gal
1 grain per liter = 0.0000386267 stones per gallon.
Real-world example
1,000 gr/L × 0.00003862665086 = 0.0386266509 st/gal
1,000 grains per liter = 0.0386266509 stones per gallon.

Frequently asked questions
How many stones per gallon are in 1 grain per liter?
1 grain per liter equals 0.0000386267 stones per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert grain per liter to stone per gallon?
Multiply the grain per liter value by 0.00003862665086. The converter above does this instantly to whatever precision you set.
How do I convert stone per gallon back to grain per liter?
Use the reverse factor: 1 stone per gallon equals 25,888.86113 grains per liter. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per liter?
Grain per Liter (gr/L) is a unit of density.
What is a stone per gallon?
Stone per Gallon (st/gal) is a unit of density.
Is the grain per liter to stone per gallon conversion exact?
Yes. Both grain per liter and stone per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.00003862665086 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.
