About Converting Grains per Cup to Slugs per Pint
Grain 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 = grains per cup × 0.00000888027147759
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per cup equals 0.273888976724 base units, and 1 slug per pint equals 30842.4103267 base units, so dividing one by the other gives the direct grain per cup-to-slug per pint factor of 0.00000888027147759.
Simple example
1 gr/cup × 0.000008880271478 = 0.0000088803 slug/pt
1 grain per cup = 0.0000088803 slugs per pint.
Real-world example
1,000 gr/cup × 0.000008880271478 = 0.0088802715 slug/pt
1,000 grains per cup = 0.0088802715 slugs per pint.

Frequently asked questions
How many slugs per pint are in 1 grain per cup?
1 grain per cup equals 0.0000088803 slugs per pint, using the exact defined conversion factor rather than an estimate.
How do I convert grain per cup to slug per pint?
Multiply the grain per cup value by 0.000008880271478. The converter above does this instantly to whatever precision you set.
How do I convert slug per pint back to grain per cup?
Use the reverse factor: 1 slug per pint equals 112,609.1699 grains per cup. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per cup?
Grain per Cup (gr/cup) is a unit of density.
What is a slug per pint?
Slug per Pint (slug/pt) is a unit of density.
Is the grain per cup to slug per pint conversion exact?
Yes. Both grain per cup and slug per pint are defined by fixed standards rather than physical artifacts, so the factor of 0.000008880271478 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.
