About Converting Grams per Pint to Grains per Gallon
Gram per Pint and Grain 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
grains per gallon = grams per pint × 123.458866824
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 grain per gallon equals 0.0171180610453 base units, so dividing one by the other gives the direct gram per pint-to-grain per gallon factor of 123.458866824.
Simple example
1 g/pt × 123.4588668 = 123.4588668 gr/gal
1 gram per pint = 123.4588668 grains per gallon.
Real-world example
1,000 g/pt × 123.4588668 = 123,458.8668 gr/gal

How do I convert grain per gallon back to gram per pint?
Use the reverse factor: 1 grain per gallon equals 0.0080998638 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 grain per gallon?
Grain per Gallon (gr/gal) is a unit of density.
Is the gram per pint to grain per gallon conversion exact?
Yes. Both gram per pint and grain per gallon are defined by fixed standards rather than physical artifacts, so the factor of 123.4588668 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.
