About Converting Grams per Pint to Drams per Gallon
Gram per Pint 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 = grams per pint × 4.51506712955
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per pint equals 2.11337641887 base units, and 1 dram per gallon equals 0.468071981707 base units, so dividing one by the other gives the direct gram per pint-to-dram per gallon factor of 4.51506712955.
Simple example
1 g/pt × 4.51506713 = 4.51506713 dr/gal
1 gram per pint = 4.51506713 drams per gallon.
Real-world example
1,000 g/pt × 4.51506713 = 4,515.06713 dr/gal
1,000 grams per pint = 4,515.06713 drams per gallon.

How do I convert dram per gallon back to gram per pint?
Use the reverse factor: 1 dram per gallon equals 0.2214806494 grams per pint. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per pint?
Gram per Pint (g/pt) is a unit of density.
What is a dram per gallon?
Dram per Gallon (dr/gal) is a unit of density.
Is the gram per pint to dram per gallon conversion exact?
Yes. Both gram per pint and dram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 4.51506713 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.
