About Converting Milligrams per Gallon to Slugs per Cubic yard
Milligram per Gallon 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 = milligrams per gallon × 0.000013839616917
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per gallon equals 0.000264172052358 base units, and 1 slug per cubic yard equals 19.0881043849 base units, so dividing one by the other gives the direct milligram per gallon-to-slug per cubic yard factor of 0.000013839616917.
Simple example
1 mg/gal × 0.00001383961692 = 0.0000138396 slug/yd3
1 milligram per gallon = 0.0000138396 slugs per cubic yard.
Real-world example
1,000 mg/gal × 0.00001383961692 = 0.0138396169 slug/yd3
1,000 milligrams per gallon = 0.0138396169 slugs per cubic yard.

What is a milligram per gallon?
Milligram per Gallon (mg/gal) 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 milligram per gallon to slug per cubic yard conversion exact?
Yes. Both milligram per gallon and slug per cubic yard are defined by fixed standards rather than physical artifacts, so the factor of 0.00001383961692 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.
