About Converting Grams per Gallon to Grains per Gallon
Gram per Gallon 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 gallon × 15.4323583529
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per gallon equals 0.264172052358 base units, and 1 grain per gallon equals 0.0171180610453 base units, so dividing one by the other gives the direct gram per gallon-to-grain per gallon factor of 15.4323583529.
Simple example
1 g/gal × 15.43235835 = 15.43235835 gr/gal
1 gram per gallon = 15.43235835 grains per gallon.
Real-world example
1,000 g/gal × 15.43235835 = 15,432.35835 gr/gal
1,000 grams per gallon = 15,432.35835 grains per gallon.

How do I convert grain per gallon back to gram per gallon?
Use the reverse factor: 1 grain per gallon equals 0.06479891 grams per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per gallon?
Gram per Gallon (g/gal) 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 gallon to grain per gallon conversion exact?
Yes. Both gram per gallon and grain per gallon are defined by fixed standards rather than physical artifacts, so the factor of 15.43235835 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.
