About Converting Stones per Liter to Slugs per Gallon
Stone per Liter and Slug per Gallon 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 gallon = stones per liter × 1.64715873052
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per liter equals 6350.29318 base units, and 1 slug per gallon equals 3855.30129084 base units, so dividing one by the other gives the direct stone per liter-to-slug per gallon factor of 1.64715873052.
Simple example
1 st/L × 1.647158731 = 1.647158731 slug/gal
1 stone per liter = 1.647158731 slugs per gallon.
Real-world example
1,000 st/L × 1.647158731 = 1,647.158731 slug/gal
1,000 stones per liter = 1,647.158731 slugs per gallon.

How do I convert slug per gallon back to stone per liter?
Use the reverse factor: 1 slug per gallon equals 0.6071060314 stones per liter. You can also use the swap control in the converter above to flip the direction instantly.
What is a stone per liter?
Stone per Liter (st/L) is a unit of density.
What is a slug per gallon?
Slug per Gallon (slug/gal) is a unit of density.
Is the stone per liter to slug per gallon conversion exact?
Yes. Both stone per liter and slug per gallon are defined by fixed standards rather than physical artifacts, so the factor of 1.647158731 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.
