About Converting Milligrams per Liter to Ounces per Quart
Milligram per Liter and Ounce per Quart 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
ounces per quart = milligrams per liter × 0.0000333816178081
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 ounce per quart equals 29.9566068292 base units, so dividing one by the other gives the direct milligram per liter-to-ounce per quart factor of 0.0000333816178081.
Simple example
1 mg/L × 0.00003338161781 = 0.0000333816 oz/qt
1 milligram per liter = 0.0000333816 ounces per quart.
Real-world example
1,000 mg/L × 0.00003338161781 = 0.0333816178 oz/qt
1,000 milligrams per liter = 0.0333816178 ounces per quart.

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

Frequently asked questions
How many ounces per quart are in 1 milligram per liter?
1 milligram per liter equals 0.0000333816 ounces per quart, using the exact defined conversion factor rather than an estimate.
How do I convert milligram per liter to ounce per quart?
Multiply the milligram per liter value by 0.00003338161781. The converter above does this instantly to whatever precision you set.
How do I convert ounce per quart back to milligram per liter?
Use the reverse factor: 1 ounce per quart equals 29,956.60683 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 ounce per quart?
Ounce per Quart (oz/qt) is a unit of density.
Is the milligram per liter to ounce per quart conversion exact?
Yes. Both milligram per liter and ounce per quart are defined by fixed standards rather than physical artifacts, so the factor of 0.00003338161781 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.
