About Converting Grains per Teaspoon to Drams per Quart
Grain per Teaspoon and Dram 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
drams per quart = grains per teaspoon × 7.02171428571
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per teaspoon equals 13.1466708828 base units, and 1 dram per quart equals 1.87228792683 base units, so dividing one by the other gives the direct grain per teaspoon-to-dram per quart factor of 7.02171428571.
Simple example
1 gr/tsp × 7.021714286 = 7.021714286 dr/qt
1 grain per teaspoon = 7.021714286 drams per quart.
Real-world example
1,000 gr/tsp × 7.021714286 = 7,021.714286 dr/qt
1,000 grains per teaspoon = 7,021.714286 drams per quart.

Frequently asked questions
How many drams per quart are in 1 grain per teaspoon?
1 grain per teaspoon equals 7.021714286 drams per quart, using the exact defined conversion factor rather than an estimate.
How do I convert grain per teaspoon to dram per quart?
Multiply the grain per teaspoon value by 7.021714286. The converter above does this instantly to whatever precision you set.
How do I convert dram per quart back to grain per teaspoon?
Use the reverse factor: 1 dram per quart equals 0.1424153646 grains per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
What is a dram per quart?
Dram per Quart (dr/qt) is a unit of density.
Is the grain per teaspoon to dram per quart conversion exact?
Yes. Both grain per teaspoon and dram per quart are defined by fixed standards rather than physical artifacts, so the factor of 7.021714286 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.
