About Converting Slugs per Teaspoon to Grains per Pint
Slug per Teaspoon 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 = slugs per teaspoon × 21620960.6299
This factor comes from each unit's defined relationship to the category's base unit: 1 slug per teaspoon equals 2960871.39136 base units, and 1 grain per pint equals 0.136944488362 base units, so dividing one by the other gives the direct slug per teaspoon-to-grain per pint factor of 21620960.6299.
Simple example
1 slug/tsp × 21620960.63 = 21,620,960.63 gr/pt
1 slug per teaspoon = 21,620,960.63 grains per pint.
Real-world example
1,000 slug/tsp × 21620960.63 = 21,620,960,630 gr/pt
1,000 slugs per teaspoon = 21,620,960,630 grains per pint.

Multiply the slug per teaspoon value by 21620960.63. The converter above does this instantly to whatever precision you set.
How do I convert grain per pint back to slug per teaspoon?
Use the reverse factor: 1 grain per pint equals 4.625141e-8 slugs per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a slug per teaspoon?
Slug per Teaspoon (slug/tsp) is a unit of density.
What is a grain per pint?
Grain per Pint (gr/pt) is a unit of density.
Is the slug per teaspoon to grain per pint conversion exact?
Yes. Both slug per teaspoon and grain per pint are defined by fixed standards rather than physical artifacts, so the factor of 21620960.63 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.
