About Converting Slugs per Cup to Pounds per Teaspoon
Slug 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 = slugs per cup × 0.670292678259
This factor comes from each unit's defined relationship to the category's base unit: 1 slug per cup equals 61684.8206534 base units, and 1 pound per teaspoon equals 92026.6961794 base units, so dividing one by the other gives the direct slug per cup-to-pound per teaspoon factor of 0.670292678259.
Simple example
1 slug/cup × 0.6702926783 = 0.6702926783 lb/tsp
1 slug per cup = 0.6702926783 pounds per teaspoon.
Real-world example
1,000 slug/cup × 0.6702926783 = 670.2926783 lb/tsp
1,000 slugs per cup = 670.2926783 pounds per teaspoon.
