About Converting Grains per Gallon to Grams per Cubic yard
Grain per Gallon and Gram per Cubic yard 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
grams per cubic yard = grains per gallon × 13.0876967314
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per gallon equals 0.0171180610453 base units, and 1 gram per cubic yard equals 0.00130795061931 base units, so dividing one by the other gives the direct grain per gallon-to-gram per cubic yard factor of 13.0876967314.
Simple example
1 gr/gal × 13.08769673 = 13.08769673 g/yd3
1 grain per gallon = 13.08769673 grams per cubic yard.
Real-world example
1,000 gr/gal × 13.08769673 = 13,087.69673 g/yd3
1,000 grains per gallon = 13,087.69673 grams per cubic yard.

What is a grain per gallon?
Grain per Gallon (gr/gal) is a unit of density.
What is a gram per cubic yard?
Gram per Cubic yard (g/yd3) is a unit of density.
Is the grain per gallon to gram per cubic yard conversion exact?
Yes. Both grain per gallon and gram per cubic yard are defined by fixed standards rather than physical artifacts, so the factor of 13.08769673 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.
