About Converting Carats per Cup to Picograms per Imperial gallon
Carat per Cup and Picogram per Imperial 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 imperial gallon = carats per cup × 3.84304e+12
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cup equals 0.845350567546 base units, and 1 picogram per imperial gallon equals 2.199692e-13 base units, so dividing one by the other gives the direct carat per cup-to-picogram per imperial gallon factor of 3.84304e+12.
Simple example
1 ct/cup × 3.84304e+12 = 3.84304e+12 pg/imp gal
1 carat per cup = 3.84304e+12 picograms per imperial gallon.
Real-world example
1,000 ct/cup × 3.84304e+12 = 3.84304e+15 pg/imp gal
1,000 carats per cup = 3.84304e+15 picograms per imperial gallon.

What is a carat per cup?
Carat per Cup (ct/cup) is a unit of density.
What is a picogram per imperial gallon?
Picogram per Imperial gallon (pg/imp gal) is a unit of density.
Is the carat per cup to picogram per imperial gallon conversion exact?
Yes. Both carat per cup and picogram per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 3.84304e+12 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.
