About Converting Drams per Liter to Nanograms per Gallon
Dram per Liter and Nanogram per Gallon 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 gallon = drams per liter × 6707163681.76
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per liter equals 1.77184519531 base units, and 1 nanogram per gallon equals 2.641721e-10 base units, so dividing one by the other gives the direct dram per liter-to-nanogram per gallon factor of 6707163681.76.
Simple example
1 dr/L × 6707163682 = 6,707,163,682 ng/gal
1 dram per liter = 6,707,163,682 nanograms per gallon.
Real-world example
1,000 dr/L × 6707163682 = 6.707164e+12 ng/gal
1,000 drams per liter = 6.707164e+12 nanograms per gallon.

Frequently asked questions
How many nanograms per gallon are in 1 dram per liter?
1 dram per liter equals 6,707,163,682 nanograms per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert dram per liter to nanogram per gallon?
Multiply the dram per liter value by 6707163682. The converter above does this instantly to whatever precision you set.
How do I convert nanogram per gallon back to dram per liter?
Use the reverse factor: 1 nanogram per gallon equals 1.490943e-10 drams per liter. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per liter?
Dram per Liter (dr/L) is a unit of density.
What is a nanogram per gallon?
Nanogram per Gallon (ng/gal) is a unit of density.
Is the dram per liter to nanogram per gallon conversion exact?
Yes. Both dram per liter and nanogram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 6707163682 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.
