About Converting Slugs per Teaspoon to Grains per Teaspoon
Slug per Teaspoon and Grain per Teaspoon 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 teaspoon = slugs per teaspoon × 225218.339895
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 teaspoon equals 13.1466708828 base units, so dividing one by the other gives the direct slug per teaspoon-to-grain per teaspoon factor of 225218.339895.
Simple example
1 slug/tsp × 225218.3399 = 225,218.3399 gr/tsp
1 slug per teaspoon = 225,218.3399 grains per teaspoon.
Real-world example
1,000 slug/tsp × 225218.3399 = 225,218,339.9 gr/tsp
1,000 slugs per teaspoon = 225,218,339.9 grains per teaspoon.

How do I convert grain per teaspoon back to slug per teaspoon?
Use the reverse factor: 1 grain per teaspoon equals 0.0000044401 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 teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
Is the slug per teaspoon to grain per teaspoon conversion exact?
Yes. Both slug per teaspoon and grain per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 225218.3399 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.
