About Converting Milligrams per Liter to Drams per Fluid ounce
Milligram per Liter and Dram per Fluid ounce 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. Milligram per Liter is most often used for drinking-water quality standards and contaminant limits.
Formula
drams per fluid ounce = milligrams per liter × 0.000016690808904
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per liter equals 0.001 base units, and 1 dram per fluid ounce equals 59.9132136584 base units, so dividing one by the other gives the direct milligram per liter-to-dram per fluid ounce factor of 0.000016690808904.
Simple example
1 mg/L × 0.0000166908089 = 0.0000166908 dr/fl oz
1 milligram per liter = 0.0000166908 drams per fluid ounce.
Real-world example
1,000 mg/L × 0.0000166908089 = 0.0166908089 dr/fl oz
1,000 milligrams per liter = 0.0166908089 drams per fluid ounce.

Understanding the Milligram per Liter
Milligram per Liter (mg/L) measures mass concentration. One milligram of a substance per liter of solution — for dilute water-based solutions, numerically almost identical to parts per million (ppm). It is classified as a metric derived concentration unit.
Where it's used: The standard unit for drinking-water and environmental contaminant limits worldwide (EPA, WHO)
mg/L vs. g/L. Both are metric mass-concentration units; 1,000 mg/L equals 1 g/L. mg/L is used for dilute concentrations (drinking water, blood tests), while g/L is more common for higher concentrations.
Uses of the Milligram per Liter today
- Drinking-water quality standards and contaminant limits
- Blood and serum concentration reporting in clinical medicine
- Environmental and wastewater testing
Understanding the Dram per Fluid ounce (dr/fl oz)
Mass per volume density.
Milligram per Liter — sources
- US EPA — National Primary Drinking Water Regulations — Contaminant limits are set and reported in mg/L.

Frequently asked questions
How many drams per fluid ounce are in 1 milligram per liter?
1 milligram per liter equals 0.0000166908 drams per fluid ounce, using the exact defined conversion factor rather than an estimate.
How do I convert milligram per liter to dram per fluid ounce?
Multiply the milligram per liter value by 0.0000166908089. The converter above does this instantly to whatever precision you set.
How do I convert dram per fluid ounce back to milligram per liter?
Use the reverse factor: 1 dram per fluid ounce equals 59,913.21366 milligrams per liter. You can also use the swap control in the converter above to flip the direction instantly.
What is a milligram per liter?
Milligram per Liter (mg/L) measures mass concentration. One milligram of a substance per liter of solution — for dilute water-based solutions, numerically almost identical to parts per million (ppm). It is classified as a metric derived concentration unit.
What is a dram per fluid ounce?
Dram per Fluid ounce (dr/fl oz) is a unit of density.
Is the milligram per liter to dram per fluid ounce conversion exact?
Yes. Both milligram per liter and dram per fluid ounce are defined by fixed standards rather than physical artifacts, so the factor of 0.0000166908089 used above is exact to as many digits as you choose to display.
What is the difference between mg/l vs. g/l?
Both are metric mass-concentration units; 1,000 mg/L equals 1 g/L. mg/L is used for dilute concentrations (drinking water, blood tests), while g/L is more common for higher concentrations.
