About Converting Grains per Cubic Millimeter to Kilograms per Quart
Grain per Cubic Millimeter and Kilogram per Quart 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
kilograms per quart = grains per cubic millimeter × 61.3226393761
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per cubic millimeter equals 64798.91 base units, and 1 kilogram per quart equals 1056.68820943 base units, so dividing one by the other gives the direct grain per cubic millimeter-to-kilogram per quart factor of 61.3226393761.
Simple example
1 gr/mm3 × 61.32263938 = 61.32263938 kg/qt
1 grain per cubic millimeter = 61.32263938 kilograms per quart.
Real-world example
1,000 gr/mm3 × 61.32263938 = 61,322.63938 kg/qt
1,000 grains per cubic millimeter = 61,322.63938 kilograms per quart.

Frequently asked questions
How many kilograms per quart are in 1 grain per cubic millimeter?
1 grain per cubic millimeter equals 61.32263938 kilograms per quart, using the exact defined conversion factor rather than an estimate.
How do I convert grain per cubic millimeter to kilogram per quart?
Multiply the grain per cubic millimeter value by 61.32263938. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per quart back to grain per cubic millimeter?
Use the reverse factor: 1 kilogram per quart equals 0.0163071911 grains per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per cubic millimeter?
Grain per Cubic Millimeter (gr/mm3) is a unit of density.
What is a kilogram per quart?
Kilogram per Quart (kg/qt) is a unit of density.
Is the grain per cubic millimeter to kilogram per quart conversion exact?
Yes. Both grain per cubic millimeter and kilogram per quart are defined by fixed standards rather than physical artifacts, so the factor of 61.32263938 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.
