About Converting Grains per Cubic foot to Grains per Quart
Grain per Cubic foot and Grain 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
grains per quart = grains per cubic foot × 0.0334201388889
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per cubic foot equals 0.00228835191057 base units, and 1 grain per quart equals 0.0684722441811 base units, so dividing one by the other gives the direct grain per cubic foot-to-grain per quart factor of 0.0334201388889.
Simple example
1 gr/ft3 × 0.03342013889 = 0.0334201389 gr/qt
1 grain per cubic foot = 0.0334201389 grains per quart.
Real-world example
1,000 gr/ft3 × 0.03342013889 = 33.42013889 gr/qt
1,000 grains per cubic foot = 33.42013889 grains per quart.

Frequently asked questions
How many grains per quart are in 1 grain per cubic foot?
1 grain per cubic foot equals 0.0334201389 grains per quart, using the exact defined conversion factor rather than an estimate.
How do I convert grain per cubic foot to grain per quart?
Multiply the grain per cubic foot value by 0.03342013889. The converter above does this instantly to whatever precision you set.
How do I convert grain per quart back to grain per cubic foot?
Use the reverse factor: 1 grain per quart equals 29.92207792 grains per cubic foot. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per cubic foot?
Grain per Cubic foot (gr/ft3) is a unit of density.
What is a grain per quart?
Grain per Quart (gr/qt) is a unit of density.
Is the grain per cubic foot to grain per quart conversion exact?
Yes. Both grain per cubic foot and grain per quart are defined by fixed standards rather than physical artifacts, so the factor of 0.03342013889 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.
