About Converting Drams per Cup to US hundredweights per Teaspoon
Dram per Cup and US hundredweight 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
us hundredweights per teaspoon = drams per cup × 8.138021e-7
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 us hundredweight per teaspoon equals 9202669.61794 base units, so dividing one by the other gives the direct dram per cup-to-us hundredweight per teaspoon factor of 8.138021e-7.
Simple example
1 dr/cup × 8.138021e-7 = 8.138021e-7 cwt/tsp
1 dram per cup = 8.138021e-7 us hundredweights per teaspoon.
