About Converting Grains per Teaspoon to Stones per Pint
Grain per Teaspoon and Stone 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
stones per pint = grains per teaspoon × 0.000979591836735
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per teaspoon equals 13.1466708828 base units, and 1 stone per pint equals 13420.5598595 base units, so dividing one by the other gives the direct grain per teaspoon-to-stone per pint factor of 0.000979591836735.
Simple example
1 gr/tsp × 0.0009795918367 = 0.0009795918 st/pt
1 grain per teaspoon = 0.0009795918 stones per pint.
Real-world example
1,000 gr/tsp × 0.0009795918367 = 0.9795918367 st/pt
1,000 grains per teaspoon = 0.9795918367 stones per pint.

How do I convert stone per pint back to grain per teaspoon?
Use the reverse factor: 1 stone per pint equals 1,020.833333 grains per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
What is a stone per pint?
Stone per Pint (st/pt) is a unit of density.
Is the grain per teaspoon to stone per pint conversion exact?
Yes. Both grain per teaspoon and stone per pint are defined by fixed standards rather than physical artifacts, so the factor of 0.0009795918367 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.
