About Converting Slugs per Pint to Grains per Cup
Slug per Pint and Grain 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
grains per cup = slugs per pint × 112609.169947
This factor comes from each unit's defined relationship to the category's base unit: 1 slug per pint equals 30842.4103267 base units, and 1 grain per cup equals 0.273888976724 base units, so dividing one by the other gives the direct slug per pint-to-grain per cup factor of 112609.169947.
Simple example
1 slug/pt × 112609.1699 = 112,609.1699 gr/cup
1 slug per pint = 112,609.1699 grains per cup.
Real-world example
1,000 slug/pt × 112609.1699 = 112,609,169.9 gr/cup
1,000 slugs per pint = 112,609,169.9 grains per cup.

How do I convert grain per cup back to slug per pint?
Use the reverse factor: 1 grain per cup equals 0.0000088803 slugs per pint. You can also use the swap control in the converter above to flip the direction instantly.
What is a slug per pint?
Slug per Pint (slug/pt) is a unit of density.
What is a grain per cup?
Grain per Cup (gr/cup) is a unit of density.
Is the slug per pint to grain per cup conversion exact?
Yes. Both slug per pint and grain per cup are defined by fixed standards rather than physical artifacts, so the factor of 112609.1699 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
