About Converting Grains per Teaspoon to Drams per Cup
Grain per Teaspoon and Dram per Cup 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 cup = grains per teaspoon × 1.75542857143
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 cup equals 7.48915170731 base units, so dividing one by the other gives the direct grain per teaspoon-to-dram per cup factor of 1.75542857143.
Simple example
1 gr/tsp × 1.755428571 = 1.755428571 dr/cup
1 grain per teaspoon = 1.755428571 drams per cup.
Real-world example
1,000 gr/tsp × 1.755428571 = 1,755.428571 dr/cup
1,000 grains per teaspoon = 1,755.428571 drams per cup.

What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
What is a dram per cup?
Dram per Cup (dr/cup) is a unit of density.
Is the grain per teaspoon to dram per cup conversion exact?
Yes. Both grain per teaspoon and dram per cup are defined by fixed standards rather than physical artifacts, so the factor of 1.755428571 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.
