About Converting Grain per Cubic inches to Ounces per Pint
Grain per Cubic inch and Ounce 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
ounces per pint = grain per cubic inches × 0.066
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per cubic inch equals 3.95427210146 base units, and 1 ounce per pint equals 59.9132136584 base units, so dividing one by the other gives the direct grain per cubic inch-to-ounce per pint factor of 0.066.
Simple example
1 gr/in3 × 0.066 = 0.066 oz/pt
1 grain per cubic inch = 0.066 ounces per pint.
Real-world example
1,000 gr/in3 × 0.066 = 66 oz/pt
1,000 grain per cubic inches = 66 ounces per pint.

Frequently asked questions
How many ounces per pint are in 1 grain per cubic inch?
1 grain per cubic inch equals 0.066 ounces per pint, using the exact defined conversion factor rather than an estimate.
How do I convert grain per cubic inch to ounce per pint?
Multiply the grain per cubic inch value by 0.066. The converter above does this instantly to whatever precision you set.
How do I convert ounce per pint back to grain per cubic inch?
Use the reverse factor: 1 ounce per pint equals 15.15151515 grain per cubic inches. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per cubic inch?
Grain per Cubic inch (gr/in3) is a unit of density.
What is a ounce per pint?
Ounce per Pint (oz/pt) is a unit of density.
Is the grain per cubic inch to ounce per pint conversion exact?
Yes. Both grain per cubic inch and ounce per pint are defined by fixed standards rather than physical artifacts, so the factor of 0.066 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.
