About Converting Milligrams per Liter to Grams per Cubic Centimeter
Milligram per Liter and Gram per Cubic Centimeter 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 typically associated with the standard unit for drinking-water and environmental contaminant limits worldwide (EPA, WHO), while Gram per Cubic Centimeter is typically associated with standard density unit in chemistry and materials science worldwide.
Formula
grams per cubic centimeter = milligrams per liter × 0.000001
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 gram per cubic centimeter equals 1000 base units, so dividing one by the other gives the direct milligram per liter-to-gram per cubic centimeter factor of 0.000001.
Simple example
1 mg/L × 0.000001 = 0.000001 g/cm3
1 milligram per liter = 0.000001 grams per cubic centimeter.
Real-world example
1,000 mg/L × 0.000001 = 0.001 g/cm3
1,000 milligrams per liter = 0.001 grams per cubic centimeter.
Conversion table
| Milligram per Liter (mg/L) | Gram per Cubic Centimeter (g/cm3) |
|---|---|
| 0.1 mg/L | 1e-7 g/cm3 |
| 1 mg/L | 0.000001 g/cm3 |
| 10 mg/L | 0.00001 g/cm3 |
| 100 mg/L | 0.0001 g/cm3 |
| 1,000 mg/L | 0.001 g/cm3 |
| 10,000 mg/L | 0.01 g/cm3 |
Reverse conversion: Gram per Cubic Centimeter to Milligram per Liter
0.000001 g/cm3 × 1000000 = 1 mg/L
0.000001 grams per cubic centimeter = 1 milligrams per liter.
milligrams per liter = grams per cubic centimeter × 1000000

Milligram per Liter vs. Gram per Cubic Centimeter
| Aspect | Milligram per Liter | Gram per Cubic Centimeter |
|---|---|---|
| Family | metric derived concentration unit | metric derived density unit |
| Typical use | Drinking-water quality standards and contaminant limits | Material identification in chemistry and geology (mineral density tables) |
| Where it's used | The standard unit for drinking-water and environmental contaminant limits worldwide (EPA, WHO) | Standard density unit in chemistry and materials science worldwide |
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 Gram per Cubic Centimeter
Gram per Cubic Centimeter (g/cm3) measures density. Numerically identical to kilograms per liter, since one cubic centimeter equals one milliliter — this is the form most commonly used in chemistry and materials-science textbooks. It is classified as a metric derived density unit.
Where it's used: Standard density unit in chemistry and materials science worldwide
Uses of the Gram per Cubic Centimeter today
- Material identification in chemistry and geology (mineral density tables)
- Materials science and engineering specifications
- Laboratory density measurements

Frequently asked questions
How many grams per cubic centimeter are in 1 milligram per liter?
1 milligram per liter equals 0.000001 grams per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert milligram per liter to gram per cubic centimeter?
Multiply the milligram per liter value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert gram per cubic centimeter back to milligram per liter?
Use the reverse factor: 1 gram per cubic centimeter equals 1,000,000 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 gram per cubic centimeter?
Gram per Cubic Centimeter (g/cm3) measures density. Numerically identical to kilograms per liter, since one cubic centimeter equals one milliliter — this is the form most commonly used in chemistry and materials-science textbooks. It is classified as a metric derived density unit.
Is the milligram per liter to gram per cubic centimeter conversion exact?
Yes. Both milligram per liter and gram per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 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.
Where is the milligram per liter still used today?
The standard unit for drinking-water and environmental contaminant limits worldwide (EPA, WHO)
