Convert nanogram per liter to kilogram per cubic meter
Nanogram per liter
The nanogram per liter (ng/L) is a unit of mass concentration equal to 10⁻⁹ grams per liter. It is used to quantify extremely small amounts of substances in solution, such as trace hormones, pharmaceuticals, or pollutants in water and biological fluids. One nanogram per liter is equivalent to one part per trillion (ppt) in dilute aqueous systems.
Kilogram per Cubic Meter
The kilogram per cubic meter (kg/m³) is the SI derived unit of density, defined as the mass in kilograms of a substance occupying one cubic meter of volume. It is the standard unit used in scientific and engineering contexts worldwide. The density of dry air at standard conditions is approximately 1.225 kg/m³, while water is about 1000 kg/m³.
