About Converting Drams per Gallon to Stones per Gallon
Dram per Gallon and Stone 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
stones per gallon = drams per gallon × 0.000279017857143
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 stone per gallon equals 1677.56998244 base units, so dividing one by the other gives the direct dram per gallon-to-stone per gallon factor of 0.000279017857143.
Simple example
1 dr/gal × 0.0002790178571 = 0.0002790179 st/gal
1 dram per gallon = 0.0002790179 stones per gallon.
Real-world example
1,000 dr/gal × 0.0002790178571 = 0.2790178571 st/gal
1,000 drams per gallon = 0.2790178571 stones per gallon.

How do I convert stone per gallon back to dram per gallon?
Use the reverse factor: 1 stone per gallon equals 3,584 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 stone per gallon?
Stone per Gallon (st/gal) is a unit of density.
Is the dram per gallon to stone per gallon conversion exact?
Yes. Both dram per gallon and stone per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.0002790178571 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.
