About Converting Grains per Fluid ounce to Long tons per Quart
Grain per Fluid ounce and Long ton 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
long tons per quart = grains per fluid ounce × 0.00000204081632653
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per fluid ounce equals 2.19111181379 base units, and 1 long ton per quart equals 1073644.78876 base units, so dividing one by the other gives the direct grain per fluid ounce-to-long ton per quart factor of 0.00000204081632653.
Simple example
1 gr/fl oz × 0.000002040816327 = 0.0000020408 long ton/qt
1 grain per fluid ounce = 0.0000020408 long tons per quart.
Real-world example
1,000 gr/fl oz × 0.000002040816327 = 0.0020408163 long ton/qt
1,000 grains per fluid ounce = 0.0020408163 long tons per quart.

What is a grain per fluid ounce?
Grain per Fluid ounce (gr/fl oz) is a unit of density.
What is a long ton per quart?
Long ton per Quart (long ton/qt) is a unit of density.
Is the grain per fluid ounce to long ton per quart conversion exact?
Yes. Both grain per fluid ounce and long ton per quart are defined by fixed standards rather than physical artifacts, so the factor of 0.000002040816327 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.
