About Converting Ounces per Fluid ounce to Grains per Pint
Ounce per Fluid ounce 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 = ounces per fluid ounce × 7000
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per fluid ounce equals 958.611418535 base units, and 1 grain per pint equals 0.136944488362 base units, so dividing one by the other gives the direct ounce per fluid ounce-to-grain per pint factor of 7000.
Simple example
1 oz/fl oz × 7000 = 7,000 gr/pt
1 ounce per fluid ounce = 7,000 grains per pint.
Real-world example
1,000 oz/fl oz × 7000 = 7,000,000 gr/pt
1,000 ounces per fluid ounce = 7,000,000 grains per pint.

Frequently asked questions
How many grains per pint are in 1 ounce per fluid ounce?
1 ounce per fluid ounce equals 7,000 grains per pint, using the exact defined conversion factor rather than an estimate.
How do I convert ounce per fluid ounce to grain per pint?
Multiply the ounce per fluid ounce value by 7000. The converter above does this instantly to whatever precision you set.
How do I convert grain per pint back to ounce per fluid ounce?
Use the reverse factor: 1 grain per pint equals 0.0001428571 ounces per fluid ounce. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per fluid ounce?
Ounce per Fluid ounce (oz/fl oz) is a unit of density.
What is a grain per pint?
Grain per Pint (gr/pt) is a unit of density.
Is the ounce per fluid ounce to grain per pint conversion exact?
Yes. Both ounce per fluid ounce and grain per pint are defined by fixed standards rather than physical artifacts, so the factor of 7000 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.
