About Converting Milligrams per Gallon to Drams per Gallon
Milligram per Gallon 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 = milligrams per gallon × 0.000564383391193
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 gallon equals 0.468071981707 base units, so dividing one by the other gives the direct milligram per gallon-to-dram per gallon factor of 0.000564383391193.
Simple example
1 mg/gal × 0.0005643833912 = 0.0005643834 dr/gal
1 milligram per gallon = 0.0005643834 drams per gallon.
Real-world example
1,000 mg/gal × 0.0005643833912 = 0.5643833912 dr/gal
1,000 milligrams per gallon = 0.5643833912 drams per gallon.

Frequently asked questions
How many drams per gallon are in 1 milligram per gallon?
1 milligram per gallon equals 0.0005643834 drams per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert milligram per gallon to dram per gallon?
Multiply the milligram per gallon value by 0.0005643833912. The converter above does this instantly to whatever precision you set.
How do I convert dram per gallon back to milligram per gallon?
Use the reverse factor: 1 dram per gallon equals 1,771.845195 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 gallon?
Dram per Gallon (dr/gal) is a unit of density.
Is the milligram per gallon to dram per gallon conversion exact?
Yes. Both milligram per gallon and dram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.0005643833912 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.
