About Converting Picograms per Cubic foot to Carats per Cubic foot
Picogram per Cubic foot and Carat per Cubic foot 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 foot = picograms per cubic foot × 5e-12
This factor comes from each unit's defined relationship to the category's base unit: 1 picogram per cubic foot equals 3.531467e-14 base units, and 1 carat per cubic foot equals 0.0070629333443 base units, so dividing one by the other gives the direct picogram per cubic foot-to-carat per cubic foot factor of 5e-12.
Simple example
1 pg/ft3 × 5e-12 = 5e-12 ct/ft3
1 picogram per cubic foot = 5e-12 carats per cubic foot.
Real-world example
1,000 pg/ft3 × 5e-12 = 5e-9 ct/ft3
1,000 picograms per cubic foot = 5e-9 carats per cubic foot.

Frequently asked questions
How many carats per cubic foot are in 1 picogram per cubic foot?
1 picogram per cubic foot equals 5e-12 carats per cubic foot, using the exact defined conversion factor rather than an estimate.
How do I convert picogram per cubic foot to carat per cubic foot?
Multiply the picogram per cubic foot value by 5e-12. The converter above does this instantly to whatever precision you set.
How do I convert carat per cubic foot back to picogram per cubic foot?
Use the reverse factor: 1 carat per cubic foot equals 200,000,000,000 picograms per cubic foot. You can also use the swap control in the converter above to flip the direction instantly.
What is a picogram per cubic foot?
Picogram per Cubic foot (pg/ft3) is a unit of density.
What is a carat per cubic foot?
Carat per Cubic foot (ct/ft3) is a unit of density.
Is the picogram per cubic foot to carat per cubic foot conversion exact?
Yes. Both picogram per cubic foot and carat per cubic foot 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.
