About Converting Picograms per Imperial gallon to Carats per Imperial gallon
Picogram per Imperial gallon and Carat 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
carats per imperial gallon = picograms per imperial gallon × 5e-12
This factor comes from each unit's defined relationship to the category's base unit: 1 picogram per imperial gallon equals 2.199692e-13 base units, and 1 carat per imperial gallon equals 0.0439938496598 base units, so dividing one by the other gives the direct picogram per imperial gallon-to-carat per imperial gallon factor of 5e-12.
Simple example
1 pg/imp gal × 5e-12 = 5e-12 ct/imp gal
1 picogram per imperial gallon = 5e-12 carats per imperial gallon.
Real-world example
1,000 pg/imp gal × 5e-12 = 5e-9 ct/imp gal
1,000 picograms per imperial gallon = 5e-9 carats per imperial gallon.

Frequently asked questions
How many carats per imperial gallon are in 1 picogram per imperial gallon?
1 picogram per imperial gallon equals 5e-12 carats per imperial gallon, using the exact defined conversion factor rather than an estimate.
How do I convert picogram per imperial gallon to carat per imperial gallon?
Multiply the picogram per imperial gallon value by 5e-12. The converter above does this instantly to whatever precision you set.
How do I convert carat per imperial gallon back to picogram per imperial gallon?
Use the reverse factor: 1 carat per imperial gallon equals 200,000,000,000 picograms per imperial gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a picogram per imperial gallon?
Picogram per Imperial gallon (pg/imp gal) is a unit of density.
What is a carat per imperial gallon?
Carat per Imperial gallon (ct/imp gal) is a unit of density.
Is the picogram per imperial gallon to carat per imperial gallon conversion exact?
Yes. Both picogram per imperial gallon and carat per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 5e-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.
