About Converting Slugs per Cup to Stones per Cup
Slug per Cup and Stone 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
stones per cup = slugs per cup × 2.29814632546
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 stone per cup equals 26841.119719 base units, so dividing one by the other gives the direct slug per cup-to-stone per cup factor of 2.29814632546.
Simple example
1 slug/cup × 2.298146325 = 2.298146325 st/cup
1 slug per cup = 2.298146325 stones per cup.
Real-world example
1,000 slug/cup × 2.298146325 = 2,298.146325 st/cup
