About Converting Grains per Milliliter to Stones per Quart
Grain per Milliliter and Stone 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
stones per quart = grains per milliliter × 0.00965666271429
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per milliliter equals 64.79891 base units, and 1 stone per quart equals 6710.27992975 base units, so dividing one by the other gives the direct grain per milliliter-to-stone per quart factor of 0.00965666271429.
Simple example
1 gr/mL × 0.009656662714 = 0.0096566627 st/qt
1 grain per milliliter = 0.0096566627 stones per quart.
Real-world example
1,000 gr/mL × 0.009656662714 = 9.656662714 st/qt
1,000 grains per milliliter = 9.656662714 stones per quart.

Frequently asked questions
How many stones per quart are in 1 grain per milliliter?
1 grain per milliliter equals 0.0096566627 stones per quart, using the exact defined conversion factor rather than an estimate.
How do I convert grain per milliliter to stone per quart?
Multiply the grain per milliliter value by 0.009656662714. The converter above does this instantly to whatever precision you set.
How do I convert stone per quart back to grain per milliliter?
Use the reverse factor: 1 stone per quart equals 103.5554445 grains per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per milliliter?
Grain per Milliliter (gr/mL) is a unit of density.
What is a stone per quart?
Stone per Quart (st/qt) is a unit of density.
Is the grain per milliliter to stone per quart conversion exact?
Yes. Both grain per milliliter and stone per quart are defined by fixed standards rather than physical artifacts, so the factor of 0.009656662714 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.
