About Converting Grains per Cubic Centimeter to Pounds per Cup
Grain per Cubic Centimeter and Pound 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
pounds per cup = grains per cubic centimeter × 0.0337983195
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per cubic centimeter equals 64.79891 base units, and 1 pound per cup equals 1917.22283707 base units, so dividing one by the other gives the direct grain per cubic centimeter-to-pound per cup factor of 0.0337983195.
Simple example
1 gr/cm3 × 0.0337983195 = 0.0337983195 lb/cup
1 grain per cubic centimeter = 0.0337983195 pounds per cup.
Real-world example
1,000 gr/cm3 × 0.0337983195 = 33.7983195 lb/cup
1,000 grains per cubic centimeter = 33.7983195 pounds per cup.

Frequently asked questions
How many pounds per cup are in 1 grain per cubic centimeter?
1 grain per cubic centimeter equals 0.0337983195 pounds per cup, using the exact defined conversion factor rather than an estimate.
How do I convert grain per cubic centimeter to pound per cup?
Multiply the grain per cubic centimeter value by 0.0337983195. The converter above does this instantly to whatever precision you set.
How do I convert pound per cup back to grain per cubic centimeter?
Use the reverse factor: 1 pound per cup equals 29.58726986 grains per cubic centimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per cubic centimeter?
Grain per Cubic Centimeter (gr/cm3) is a unit of density.
What is a pound per cup?
Pound per Cup (lb/cup) is a unit of density.
Is the grain per cubic centimeter to pound per cup conversion exact?
Yes. Both grain per cubic centimeter and pound per cup are defined by fixed standards rather than physical artifacts, so the factor of 0.0337983195 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.
