About Converting Grams per Quart to Grains per Cubic Millimeter
Gram per Quart and Grain per Cubic Millimeter 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 cubic millimeter = grams per quart × 0.0000163071911153
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per quart equals 1.05668820943 base units, and 1 grain per cubic millimeter equals 64798.91 base units, so dividing one by the other gives the direct gram per quart-to-grain per cubic millimeter factor of 0.0000163071911153.
Simple example
1 g/qt × 0.00001630719112 = 0.0000163072 gr/mm3
1 gram per quart = 0.0000163072 grains per cubic millimeter.
Real-world example
1,000 g/qt × 0.00001630719112 = 0.0163071911 gr/mm3
1,000 grams per quart = 0.0163071911 grains per cubic millimeter.

Frequently asked questions
How many grains per cubic millimeter are in 1 gram per quart?
1 gram per quart equals 0.0000163072 grains per cubic millimeter, using the exact defined conversion factor rather than an estimate.
How do I convert gram per quart to grain per cubic millimeter?
Multiply the gram per quart value by 0.00001630719112. The converter above does this instantly to whatever precision you set.
How do I convert grain per cubic millimeter back to gram per quart?
Use the reverse factor: 1 grain per cubic millimeter equals 61,322.63938 grams per quart. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per quart?
Gram per Quart (g/qt) is a unit of density.
What is a grain per cubic millimeter?
Grain per Cubic Millimeter (gr/mm3) is a unit of density.
Is the gram per quart to grain per cubic millimeter conversion exact?
Yes. Both gram per quart and grain per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.00001630719112 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.
