About Converting Slugs per Cup to Pounds per Liter
Slug per Cup and Pound per Liter 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 liter = slugs per cup × 135.991751037
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 liter equals 453.59237 base units, so dividing one by the other gives the direct slug per cup-to-pound per liter factor of 135.991751037.
Simple example
1 slug/cup × 135.991751 = 135.991751 lb/L
