About Converting Gram per Cubic inches to Grains per Pint
Gram 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 = gram per cubic inches × 445.609347441
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per cubic inch equals 61.0237440947 base units, and 1 grain per pint equals 0.136944488362 base units, so dividing one by the other gives the direct gram per cubic inch-to-grain per pint factor of 445.609347441.
Simple example
1 g/in3 × 445.6093474 = 445.6093474 gr/pt
1 gram per cubic inch = 445.6093474 grains per pint.
Real-world example
1,000 g/in3 × 445.6093474 = 445,609.3474 gr/pt
1,000 gram per cubic inches = 445,609.3474 grains per pint.

Frequently asked questions
How many grains per pint are in 1 gram per cubic inch?
1 gram per cubic inch equals 445.6093474 grains per pint, using the exact defined conversion factor rather than an estimate.
How do I convert gram per cubic inch to grain per pint?
Multiply the gram per cubic inch value by 445.6093474. The converter above does this instantly to whatever precision you set.
How do I convert grain per pint back to gram per cubic inch?
Use the reverse factor: 1 grain per pint equals 0.0022441181 gram per cubic inches. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per cubic inch?
Gram per Cubic inch (g/in3) is a unit of density.
What is a grain per pint?
Grain per Pint (gr/pt) is a unit of density.
Is the gram per cubic inch to grain per pint conversion exact?
Yes. Both gram per cubic inch and grain per pint are defined by fixed standards rather than physical artifacts, so the factor of 445.6093474 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.
