About Converting Nanograms per Liter to Picograms per Cubic Centimeter
Nanogram per Liter and Picogram 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
picograms per cubic centimeter = nanograms per liter × 1
This factor comes from each unit's defined relationship to the category's base unit: 1 nanogram per liter equals 1e-9 base units, and 1 picogram per cubic centimeter equals 1e-9 base units, so dividing one by the other gives the direct nanogram per liter-to-picogram per cubic centimeter factor of 1.
Simple example
1 ng/L × 1 = 1 pg/cm3
1 nanogram per liter = 1 picograms per cubic centimeter.
Real-world example
1,000 ng/L × 1 = 1,000 pg/cm3
1,000 nanograms per liter = 1,000 picograms per cubic centimeter.

Frequently asked questions
How many picograms per cubic centimeter are in 1 nanogram per liter?
1 nanogram per liter equals 1 picograms per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert nanogram per liter to picogram per cubic centimeter?
Multiply the nanogram per liter value by 1. The converter above does this instantly to whatever precision you set.
How do I convert picogram per cubic centimeter back to nanogram per liter?
Use the reverse factor: 1 picogram per cubic centimeter equals 1 nanograms per liter. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanogram per liter?
Nanogram per Liter (ng/L) is a unit of density.
What is a picogram per cubic centimeter?
Picogram per Cubic Centimeter (pg/cm3) is a unit of density.
Is the nanogram per liter to picogram per cubic centimeter conversion exact?
Yes. Both nanogram per liter and picogram per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 1 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.
