About Converting Troy ounces per Liter to Nanograms per Liter
Troy ounce per Liter and Nanogram 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
nanograms per liter = troy ounces per liter × 31103476800
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per liter equals 31.1034768 base units, and 1 nanogram per liter equals 1e-9 base units, so dividing one by the other gives the direct troy ounce per liter-to-nanogram per liter factor of 31103476800.
Simple example
1 oz t/L × 31103476800 = 31,103,476,800 ng/L
1 troy ounce per liter = 31,103,476,800 nanograms per liter.
Real-world example
1,000 oz t/L × 31103476800 = 3.110348e+13 ng/L
1,000 troy ounces per liter = 3.110348e+13 nanograms per liter.

Frequently asked questions
How many nanograms per liter are in 1 troy ounce per liter?
1 troy ounce per liter equals 31,103,476,800 nanograms per liter, using the exact defined conversion factor rather than an estimate.
How do I convert troy ounce per liter to nanogram per liter?
Multiply the troy ounce per liter value by 31103476800. The converter above does this instantly to whatever precision you set.
How do I convert nanogram per liter back to troy ounce per liter?
Use the reverse factor: 1 nanogram per liter equals 3.215075e-11 troy ounces per liter. You can also use the swap control in the converter above to flip the direction instantly.
What is a troy ounce per liter?
Troy ounce per Liter (oz t/L) is a unit of density.
What is a nanogram per liter?
Nanogram per Liter (ng/L) is a unit of density.
Is the troy ounce per liter to nanogram per liter conversion exact?
Yes. Both troy ounce per liter and nanogram per liter are defined by fixed standards rather than physical artifacts, so the factor of 31103476800 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.
