About Converting Nanograms per Fluid ounce to Micrograms per Liter
Nanogram per Fluid ounce and Microgram 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
micrograms per liter = nanograms per fluid ounce × 0.0338140227018
This factor comes from each unit's defined relationship to the category's base unit: 1 nanogram per fluid ounce equals 3.381402e-8 base units, and 1 microgram per liter equals 0.000001 base units, so dividing one by the other gives the direct nanogram per fluid ounce-to-microgram per liter factor of 0.0338140227018.
Simple example
1 ng/fl oz × 0.0338140227 = 0.0338140227 ug/L
1 nanogram per fluid ounce = 0.0338140227 micrograms per liter.
Real-world example
1,000 ng/fl oz × 0.0338140227 = 33.8140227 ug/L
1,000 nanograms per fluid ounce = 33.8140227 micrograms per liter.

Frequently asked questions
How many micrograms per liter are in 1 nanogram per fluid ounce?
1 nanogram per fluid ounce equals 0.0338140227 micrograms per liter, using the exact defined conversion factor rather than an estimate.
How do I convert nanogram per fluid ounce to microgram per liter?
Multiply the nanogram per fluid ounce value by 0.0338140227. The converter above does this instantly to whatever precision you set.
How do I convert microgram per liter back to nanogram per fluid ounce?
Use the reverse factor: 1 microgram per liter equals 29.57352956 nanograms per fluid ounce. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanogram per fluid ounce?
Nanogram per Fluid ounce (ng/fl oz) is a unit of density.
What is a microgram per liter?
Microgram per Liter (ug/L) is a unit of density.
Is the nanogram per fluid ounce to microgram per liter conversion exact?
Yes. Both nanogram per fluid ounce and microgram per liter are defined by fixed standards rather than physical artifacts, so the factor of 0.0338140227 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.
