About Converting Grains per Cup to Slugs per Cubic Centimeter
Grain per Cup and Slug per Cubic Centimeter 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 cubic centimeter = grains per cup × 1.876736e-8
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 cubic centimeter equals 14593902.9372 base units, so dividing one by the other gives the direct grain per cup-to-slug per cubic centimeter factor of 1.876736e-8.
Simple example
1 gr/cup × 1.876736e-8 = 1.876736e-8 slug/cm3
1 grain per cup = 1.876736e-8 slugs per cubic centimeter.
Real-world example
1,000 gr/cup × 1.876736e-8 = 0.0000187674 slug/cm3
1,000 grains per cup = 0.0000187674 slugs per cubic centimeter.

Frequently asked questions
How many slugs per cubic centimeter are in 1 grain per cup?
1 grain per cup equals 1.876736e-8 slugs per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert grain per cup to slug per cubic centimeter?
Multiply the grain per cup value by 1.876736e-8. The converter above does this instantly to whatever precision you set.
How do I convert slug per cubic centimeter back to grain per cup?
Use the reverse factor: 1 slug per cubic centimeter equals 53,284,009.86 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 cubic centimeter?
Slug per Cubic Centimeter (slug/cm3) is a unit of density.
Is the grain per cup to slug per cubic centimeter conversion exact?
Yes. Both grain per cup and slug per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 1.876736e-8 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.
