About Converting Grains per Teaspoon to Slugs per Cubic yard
Grain per Teaspoon and Slug per Cubic yard 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
slugs per cubic yard = grains per teaspoon × 0.688736325916
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 slug per cubic yard equals 19.0881043849 base units, so dividing one by the other gives the direct grain per teaspoon-to-slug per cubic yard factor of 0.688736325916.
Simple example
1 gr/tsp × 0.6887363259 = 0.6887363259 slug/yd3
1 grain per teaspoon = 0.6887363259 slugs per cubic yard.
Real-world example
1,000 gr/tsp × 0.6887363259 = 688.7363259 slug/yd3
1,000 grains per teaspoon = 688.7363259 slugs per cubic yard.

What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
What is a slug per cubic yard?
Slug per Cubic yard (slug/yd3) is a unit of density.
Is the grain per teaspoon to slug per cubic yard conversion exact?
Yes. Both grain per teaspoon and slug per cubic yard are defined by fixed standards rather than physical artifacts, so the factor of 0.6887363259 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.
