About Converting Nanograms per Cubic Meter to Grams per Liter
Nanogram per Cubic Meter and Gram per Liter 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
grams per liter = nanograms per cubic meter × 1e-12
This factor comes from each unit's defined relationship to the category's base unit: 1 nanogram per cubic meter equals 1e-12 base units, and 1 gram per liter equals 1 base unit, so dividing one by the other gives the direct nanogram per cubic meter-to-gram per liter factor of 1e-12.
Simple example
1 ng/m3 × 1e-12 = 1e-12 g/L
1 nanogram per cubic meter = 1e-12 grams per liter.
Real-world example
1,000 ng/m3 × 1e-12 = 1e-9 g/L
1,000 nanograms per cubic meter = 1e-9 grams per liter.
Conversion table
| Nanogram per Cubic Meter (ng/m3) | Gram per Liter (g/L) |
|---|---|
| 0.1 ng/m3 | 1e-13 g/L |
| 1 ng/m3 | 1e-12 g/L |
| 10 ng/m3 | 1e-11 g/L |
| 100 ng/m3 | 1e-10 g/L |
| 1,000 ng/m3 | 1e-9 g/L |
| 10,000 ng/m3 | 1e-8 g/L |
Reverse conversion: Gram per Liter to Nanogram per Cubic Meter
1e-12 g/L × 1000000000000 = 1 ng/m3
1e-12 grams per liter = 1 nanograms per cubic meter.
nanograms per cubic meter = grams per liter × 1000000000000

Frequently asked questions
How many grams per liter are in 1 nanogram per cubic meter?
1 nanogram per cubic meter equals 1e-12 grams per liter, using the exact defined conversion factor rather than an estimate.
How do I convert nanogram per cubic meter to gram per liter?
Multiply the nanogram per cubic meter value by 1e-12. The converter above does this instantly to whatever precision you set.
How do I convert gram per liter back to nanogram per cubic meter?
Use the reverse factor: 1 gram per liter equals 1,000,000,000,000 nanograms per cubic meter. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanogram per cubic meter?
Nanogram per Cubic Meter (ng/m3) is a unit of density.
What is a gram per liter?
Gram per Liter (g/L) measures mass concentration. One gram of a substance dissolved or dispersed per liter of total solution or mixture volume. It is classified as a metric derived concentration unit.
Is the nanogram per cubic meter to gram per liter conversion exact?
Yes. Both nanogram per cubic meter and gram per liter are defined by fixed standards rather than physical artifacts, so the factor of 1e-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.
