About Converting Drams per Cup to Pounds per Teaspoon
Dram per Cup and Pound per Teaspoon 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
pounds per teaspoon = drams per cup × 0.0000813802083333
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per cup equals 7.48915170731 base units, and 1 pound per teaspoon equals 92026.6961794 base units, so dividing one by the other gives the direct dram per cup-to-pound per teaspoon factor of 0.0000813802083333.
Simple example
1 dr/cup × 0.00008138020833 = 0.0000813802 lb/tsp
1 dram per cup = 0.0000813802 pounds per teaspoon.
Real-world example
1,000 dr/cup × 0.00008138020833 = 0.0813802083 lb/tsp
1,000 drams per cup = 0.0813802083 pounds per teaspoon.
