About Converting Carats per Fluid ounce to Grains per Quart
Carat per Fluid ounce 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 = carats per fluid ounce × 98.7670934588
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per fluid ounce equals 6.76280454037 base units, and 1 grain per quart equals 0.0684722441811 base units, so dividing one by the other gives the direct carat per fluid ounce-to-grain per quart factor of 98.7670934588.
Simple example
1 ct/fl oz × 98.76709346 = 98.76709346 gr/qt
1 carat per fluid ounce = 98.76709346 grains per quart.
Real-world example
1,000 ct/fl oz × 98.76709346 = 98,767.09346 gr/qt
1,000 carats per fluid ounce = 98,767.09346 grains per quart.

What is a carat per fluid ounce?
Carat per Fluid ounce (ct/fl oz) is a unit of density.
What is a grain per quart?
Grain per Quart (gr/qt) is a unit of density.
Is the carat per fluid ounce to grain per quart conversion exact?
Yes. Both carat per fluid ounce and grain per quart are defined by fixed standards rather than physical artifacts, so the factor of 98.76709346 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.
