About Converting Carats per Liter to Picograms per Gallon
Carat per Liter 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 = carats per liter × 757082356800
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per liter equals 0.2 base units, and 1 picogram per gallon equals 2.641721e-13 base units, so dividing one by the other gives the direct carat per liter-to-picogram per gallon factor of 757082356800.
Simple example
1 ct/L × 757082356800 = 757,082,356,800 pg/gal
1 carat per liter = 757,082,356,800 picograms per gallon.
Real-world example
1,000 ct/L × 757082356800 = 7.570824e+14 pg/gal
1,000 carats per liter = 7.570824e+14 picograms per gallon.

Frequently asked questions
How many picograms per gallon are in 1 carat per liter?
1 carat per liter equals 757,082,356,800 picograms per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert carat per liter to picogram per gallon?
Multiply the carat per liter value by 757082356800. The converter above does this instantly to whatever precision you set.
How do I convert picogram per gallon back to carat per liter?
Use the reverse factor: 1 picogram per gallon equals 1.32086e-12 carats per liter. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per liter?
Carat per Liter (ct/L) is a unit of density.
What is a picogram per gallon?
Picogram per Gallon (pg/gal) is a unit of density.
Is the carat per liter to picogram per gallon conversion exact?
Yes. Both carat per liter and picogram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 757082356800 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.
