About Converting Troy ounces per Fluid ounce to Grains per Pint
Troy 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 = troy ounces per fluid ounce × 7680
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per fluid ounce equals 1051.73367062 base units, and 1 grain per pint equals 0.136944488362 base units, so dividing one by the other gives the direct troy ounce per fluid ounce-to-grain per pint factor of 7680.
Simple example
1 oz t/fl oz × 7680 = 7,680 gr/pt
1 troy ounce per fluid ounce = 7,680 grains per pint.
Real-world example
1,000 oz t/fl oz × 7680 = 7,680,000 gr/pt
1,000 troy ounces per fluid ounce = 7,680,000 grains per pint.

Frequently asked questions
How many grains per pint are in 1 troy ounce per fluid ounce?
1 troy ounce per fluid ounce equals 7,680 grains per pint, using the exact defined conversion factor rather than an estimate.
How do I convert troy ounce per fluid ounce to grain per pint?
Multiply the troy ounce per fluid ounce value by 7680. The converter above does this instantly to whatever precision you set.
How do I convert grain per pint back to troy ounce per fluid ounce?
Use the reverse factor: 1 grain per pint equals 0.0001302083 troy ounces per fluid ounce. You can also use the swap control in the converter above to flip the direction instantly.
What is a troy ounce per fluid ounce?
Troy ounce per Fluid ounce (oz t/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 troy ounce per fluid ounce to grain per pint conversion exact?
Yes. Both troy ounce per fluid ounce and grain per pint are defined by fixed standards rather than physical artifacts, so the factor of 7680 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.
