About Converting Picograms per Cubic Millimeter to Carats per Cubic Centimeter
Picogram per Cubic Millimeter and Carat per Cubic Centimeter 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 cubic centimeter = picograms per cubic millimeter × 5e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 picogram per cubic millimeter equals 0.000001 base units, and 1 carat per cubic centimeter equals 200 base units, so dividing one by the other gives the direct picogram per cubic millimeter-to-carat per cubic centimeter factor of 5e-9.
Simple example
1 pg/mm3 × 5e-9 = 5e-9 ct/cm3
1 picogram per cubic millimeter = 5e-9 carats per cubic centimeter.
Real-world example
1,000 pg/mm3 × 5e-9 = 0.000005 ct/cm3
1,000 picograms per cubic millimeter = 0.000005 carats per cubic centimeter.
Conversion table

Reverse conversion: Carat per Cubic Centimeter to Picogram per Cubic Millimeter
5e-9 ct/cm3 × 200000000 = 1 pg/mm3
5e-9 carats per cubic centimeter = 1 picogram per cubic millimeter.
picograms per cubic millimeter = carats per cubic centimeter × 200000000

Frequently asked questions
How many carats per cubic centimeter are in 1 picogram per cubic millimeter?
1 picogram per cubic millimeter equals 5e-9 carats per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert picogram per cubic millimeter to carat per cubic centimeter?
Multiply the picogram per cubic millimeter value by 5e-9. The converter above does this instantly to whatever precision you set.
How do I convert carat per cubic centimeter back to picogram per cubic millimeter?
Use the reverse factor: 1 carat per cubic centimeter equals 200,000,000 picograms per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a picogram per cubic millimeter?
Picogram per Cubic Millimeter (pg/mm3) is a unit of density.
What is a carat per cubic centimeter?
Carat per Cubic Centimeter (ct/cm3) is a unit of density.
Is the picogram per cubic millimeter to carat per cubic centimeter conversion exact?
Yes. Both picogram per cubic millimeter and carat per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 5e-9 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.
