About Converting Grams per Teaspoon to Drams per Cup
Gram 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 = grams per teaspoon × 27.0904027773
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per teaspoon equals 202.884136211 base units, and 1 dram per cup equals 7.48915170731 base units, so dividing one by the other gives the direct gram per teaspoon-to-dram per cup factor of 27.0904027773.
Simple example
1 g/tsp × 27.09040278 = 27.09040278 dr/cup
1 gram per teaspoon = 27.09040278 drams per cup.
Real-world example
1,000 g/tsp × 27.09040278 = 27,090.40278 dr/cup
1,000 grams per teaspoon = 27,090.40278 drams per cup.

What is a gram per teaspoon?
Gram per Teaspoon (g/tsp) is a unit of density.
What is a dram per cup?
Dram per Cup (dr/cup) is a unit of density.
Is the gram per teaspoon to dram per cup conversion exact?
Yes. Both gram per teaspoon and dram per cup are defined by fixed standards rather than physical artifacts, so the factor of 27.09040278 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.
