About Converting Carat per Cubic inches to Grains per Pint
Carat per Cubic inch and Grain 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
grains per pint = carat per cubic inches × 89.1218694882
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cubic inch equals 12.2047488189 base units, and 1 grain per pint equals 0.136944488362 base units, so dividing one by the other gives the direct carat per cubic inch-to-grain per pint factor of 89.1218694882.
Simple example
1 ct/in3 × 89.12186949 = 89.12186949 gr/pt
1 carat per cubic inch = 89.12186949 grains per pint.
Real-world example
1,000 ct/in3 × 89.12186949 = 89,121.86949 gr/pt
1,000 carat per cubic inches = 89,121.86949 grains per pint.

Frequently asked questions
How many grains per pint are in 1 carat per cubic inch?
1 carat per cubic inch equals 89.12186949 grains per pint, using the exact defined conversion factor rather than an estimate.
How do I convert carat per cubic inch to grain per pint?
Multiply the carat per cubic inch value by 89.12186949. The converter above does this instantly to whatever precision you set.
How do I convert grain per pint back to carat per cubic inch?
Use the reverse factor: 1 grain per pint equals 0.0112205905 carat per cubic inches. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per cubic inch?
Carat per Cubic inch (ct/in3) is a unit of density.
What is a grain per pint?
Grain per Pint (gr/pt) is a unit of density.
Is the carat per cubic inch to grain per pint conversion exact?
Yes. Both carat per cubic inch and grain per pint are defined by fixed standards rather than physical artifacts, so the factor of 89.12186949 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.
