About Converting Grains per Cup to Centigrams per Pint
Grain per Cup and Centigram 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
centigrams per pint = grains per cup × 12.959782
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 centigram per pint equals 0.0211337641887 base units, so dividing one by the other gives the direct grain per cup-to-centigram per pint factor of 12.959782.
Simple example
1 gr/cup × 12.959782 = 12.959782 cg/pt
1 grain per cup = 12.959782 centigrams per pint.
Real-world example
1,000 gr/cup × 12.959782 = 12,959.782 cg/pt
1,000 grains per cup = 12,959.782 centigrams per pint.

Frequently asked questions
How many centigrams per pint are in 1 grain per cup?
1 grain per cup equals 12.959782 centigrams per pint, using the exact defined conversion factor rather than an estimate.
How do I convert grain per cup to centigram per pint?
Multiply the grain per cup value by 12.959782. The converter above does this instantly to whatever precision you set.
How do I convert centigram per pint back to grain per cup?
Use the reverse factor: 1 centigram per pint equals 0.0771617918 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 centigram per pint?
Centigram per Pint (cg/pt) is a unit of density.
Is the grain per cup to centigram per pint conversion exact?
Yes. Both grain per cup and centigram per pint are defined by fixed standards rather than physical artifacts, so the factor of 12.959782 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.
