About Converting Drams per Teaspoon to Grams per Cup
Dram per Teaspoon and Gram 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
grams per cup = drams per teaspoon × 85.048569375
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per teaspoon equals 359.479281951 base units, and 1 gram per cup equals 4.22675283773 base units, so dividing one by the other gives the direct dram per teaspoon-to-gram per cup factor of 85.048569375.
Simple example
1 dr/tsp × 85.04856938 = 85.04856938 g/cup
1 dram per teaspoon = 85.04856938 grams per cup.
Real-world example

What is a dram per teaspoon?
Dram per Teaspoon (dr/tsp) is a unit of density.
What is a gram per cup?
Gram per Cup (g/cup) is a unit of density.
Is the dram per teaspoon to gram per cup conversion exact?
