About Converting Grains per Liter to Drams per Gallon
Grain per Liter and Dram 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
drams per gallon = grains per liter × 0.138437916672
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 dram per gallon equals 0.468071981707 base units, so dividing one by the other gives the direct grain per liter-to-dram per gallon factor of 0.138437916672.
Simple example
1 gr/L × 0.1384379167 = 0.1384379167 dr/gal
1 grain per liter = 0.1384379167 drams per gallon.
Real-world example
1,000 gr/L × 0.1384379167 = 138.4379167 dr/gal
1,000 grains per liter = 138.4379167 drams per gallon.

Frequently asked questions
How many drams per gallon are in 1 grain per liter?
1 grain per liter equals 0.1384379167 drams per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert grain per liter to dram per gallon?
Multiply the grain per liter value by 0.1384379167. The converter above does this instantly to whatever precision you set.
How do I convert dram per gallon back to grain per liter?
Use the reverse factor: 1 dram per gallon equals 7.223454557 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 dram per gallon?
Dram per Gallon (dr/gal) is a unit of density.
Is the grain per liter to dram per gallon conversion exact?
Yes. Both grain per liter and dram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.1384379167 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.
