About Converting Slugs per Tablespoon to Picograms per Gallon
Slug per Tablespoon and Picogram 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
picograms per gallon = slugs per tablespoon × 3.736039e+18
This factor comes from each unit's defined relationship to the category's base unit: 1 slug per tablespoon equals 986957.130454 base units, and 1 picogram per gallon equals 2.641721e-13 base units, so dividing one by the other gives the direct slug per tablespoon-to-picogram per gallon factor of 3.736039e+18.
Simple example
1 slug/tbsp × 3.736039e+18 = 3.736039e+18 pg/gal
1 slug per tablespoon = 3.736039e+18 picograms per gallon.
Real-world example
1,000 slug/tbsp × 3.736039e+18 = 3.736039e+21 pg/gal
1,000 slugs per tablespoon = 3.736039e+21 picograms per gallon.

What is a slug per tablespoon?
Slug per Tablespoon (slug/tbsp) is a unit of density.
What is a picogram per gallon?
Picogram per Gallon (pg/gal) is a unit of density.
Is the slug per tablespoon to picogram per gallon conversion exact?
Yes. Both slug per tablespoon and picogram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 3.736039e+18 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.
