About Converting Slugs per Teaspoon to Kilograms per Cup
Slug per Teaspoon and Kilogram per Cup 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
kilograms per cup = slugs per teaspoon × 700.507340986
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 kilogram per cup equals 4226.75283773 base units, so dividing one by the other gives the direct slug per teaspoon-to-kilogram per cup factor of 700.507340986.
Simple example
1 slug/tsp × 700.507341 = 700.507341 kg/cup
1 slug per teaspoon = 700.507341 kilograms per cup.
Real-world example
1,000 slug/tsp × 700.507341 = 700,507.341 kg/cup
1,000 slugs per teaspoon = 700,507.341 kilograms per cup.

What is a slug per teaspoon?
Slug per Teaspoon (slug/tsp) is a unit of density.
What is a kilogram per cup?
Kilogram per Cup (kg/cup) is a unit of density.
Is the slug per teaspoon to kilogram per cup conversion exact?
Yes. Both slug per teaspoon and kilogram per cup are defined by fixed standards rather than physical artifacts, so the factor of 700.507341 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.
