About Converting Milligrams per Teaspoon to Pounds per Cup
Milligram per Teaspoon and Pound 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
pounds per cup = milligrams per teaspoon × 0.000105821885849
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per teaspoon equals 0.202884136211 base units, and 1 pound per cup equals 1917.22283707 base units, so dividing one by the other gives the direct milligram per teaspoon-to-pound per cup factor of 0.000105821885849.
Simple example
1 mg/tsp × 0.0001058218858 = 0.0001058219 lb/cup
1 milligram per teaspoon = 0.0001058219 pounds per cup.
Real-world example
1,000 mg/tsp × 0.0001058218858 = 0.1058218858 lb/cup
1,000 milligrams per teaspoon = 0.1058218858 pounds per cup.
