About Converting Stones per Cup to Slugs per Pint
Stone per Cup and Slug per Pint 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
slugs per pint = stones per cup × 0.870266604804
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per cup equals 26841.119719 base units, and 1 slug per pint equals 30842.4103267 base units, so dividing one by the other gives the direct stone per cup-to-slug per pint factor of 0.870266604804.
Simple example
1 st/cup × 0.8702666048 = 0.8702666048 slug/pt
1 stone per cup = 0.8702666048 slugs per pint.
Real-world example
1,000 st/cup × 0.8702666048 = 870.2666048 slug/pt
1,000 stones per cup = 870.2666048 slugs per pint.

What is a stone per cup?
Stone per Cup (st/cup) is a unit of density.
What is a slug per pint?
Slug per Pint (slug/pt) is a unit of density.
Is the stone per cup to slug per pint conversion exact?
Yes. Both stone per cup and slug per pint are defined by fixed standards rather than physical artifacts, so the factor of 0.8702666048 used above is exact to as many digits as you choose to display.
