About Converting Stones per Liter to Grains per Gallon
Stone 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 = stones per liter × 370970.354832
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per liter equals 6350.29318 base units, and 1 grain per gallon equals 0.0171180610453 base units, so dividing one by the other gives the direct stone per liter-to-grain per gallon factor of 370970.354832.
Simple example
1 st/L × 370970.3548 = 370,970.3548 gr/gal
1 stone per liter = 370,970.3548 grains per gallon.
Real-world example
1,000 st/L × 370970.3548 = 370,970,354.8 gr/gal
1,000 stones per liter = 370,970,354.8 grains per gallon.

Frequently asked questions
How many grains per gallon are in 1 stone per liter?
1 stone per liter equals 370,970.3548 grains per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert stone per liter to grain per gallon?
Multiply the stone per liter value by 370970.3548. The converter above does this instantly to whatever precision you set.
How do I convert grain per gallon back to stone per liter?
Use the reverse factor: 1 grain per gallon equals 0.0000026956 stones per liter. You can also use the swap control in the converter above to flip the direction instantly.
What is a stone per liter?
Stone per Liter (st/L) is a unit of density.
What is a grain per gallon?
Grain per Gallon (gr/gal) is a unit of density.
Is the stone per liter to grain per gallon conversion exact?
Yes. Both stone per liter and grain per gallon are defined by fixed standards rather than physical artifacts, so the factor of 370970.3548 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.
