About Converting Drams per Gallon to Grains per Liter
Dram per Gallon and Grain per Liter 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 liter = drams per gallon × 7.22345455667
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per gallon equals 0.468071981707 base units, and 1 grain per liter equals 0.06479891 base units, so dividing one by the other gives the direct dram per gallon-to-grain per liter factor of 7.22345455667.
Simple example
1 dr/gal × 7.223454557 = 7.223454557 gr/L
1 dram per gallon = 7.223454557 grains per liter.
Real-world example
1,000 dr/gal × 7.223454557 = 7,223.454557 gr/L
1,000 drams per gallon = 7,223.454557 grains per liter.

How do I convert grain per liter back to dram per gallon?
Use the reverse factor: 1 grain per liter equals 0.1384379167 drams per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per gallon?
Dram per Gallon (dr/gal) is a unit of density.
What is a grain per liter?
Grain per Liter (gr/L) is a unit of density.
Is the dram per gallon to grain per liter conversion exact?
Yes. Both dram per gallon and grain per liter are defined by fixed standards rather than physical artifacts, so the factor of 7.223454557 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.
