About Converting Milligrams per Gallon to Drams per Liter
Milligram per Gallon and Dram 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
drams per liter = milligrams per gallon × 0.000149094318768
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per gallon equals 0.000264172052358 base units, and 1 dram per liter equals 1.77184519531 base units, so dividing one by the other gives the direct milligram per gallon-to-dram per liter factor of 0.000149094318768.
Simple example
1 mg/gal × 0.0001490943188 = 0.0001490943 dr/L
1 milligram per gallon = 0.0001490943 drams per liter.
Real-world example
1,000 mg/gal × 0.0001490943188 = 0.1490943188 dr/L
1,000 milligrams per gallon = 0.1490943188 drams per liter.

Frequently asked questions
How many drams per liter are in 1 milligram per gallon?
1 milligram per gallon equals 0.0001490943 drams per liter, using the exact defined conversion factor rather than an estimate.
How do I convert milligram per gallon to dram per liter?
Multiply the milligram per gallon value by 0.0001490943188. The converter above does this instantly to whatever precision you set.
How do I convert dram per liter back to milligram per gallon?
Use the reverse factor: 1 dram per liter equals 6,707.163682 milligrams per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a milligram per gallon?
Milligram per Gallon (mg/gal) is a unit of density.
What is a dram per liter?
Dram per Liter (dr/L) is a unit of density.
Is the milligram per gallon to dram per liter conversion exact?
Yes. Both milligram per gallon and dram per liter are defined by fixed standards rather than physical artifacts, so the factor of 0.0001490943188 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.
