About Converting Grams per Cubic Centimeter to Milligrams per Liter
Gram per Cubic Centimeter and Milligram 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. Gram per Cubic Centimeter is typically associated with standard density unit in chemistry and materials science worldwide, while Milligram per Liter is typically associated with the standard unit for drinking-water and environmental contaminant limits worldwide (EPA, WHO).
Formula
milligrams per liter = grams per cubic centimeter × 1000000
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per cubic centimeter equals 1000 base units, and 1 milligram per liter equals 0.001 base units, so dividing one by the other gives the direct gram per cubic centimeter-to-milligram per liter factor of 1000000.
Simple example
1 g/cm3 × 1000000 = 1,000,000 mg/L
1 gram per cubic centimeter = 1,000,000 milligrams per liter.
Real-world example
1,000 g/cm3 × 1000000 = 1,000,000,000 mg/L
1,000 grams per cubic centimeter = 1,000,000,000 milligrams per liter.
Conversion table

Reverse conversion: Milligram per Liter to Gram per Cubic Centimeter
1 mg/L × 0.000001 = 0.000001 g/cm3
1 milligram per liter = 0.000001 grams per cubic centimeter.
grams per cubic centimeter = milligrams per liter × 0.000001

Gram per Cubic Centimeter vs. Milligram per Liter
| Aspect | Gram per Cubic Centimeter | Milligram per Liter |
|---|---|---|
| Family | metric derived density unit | metric derived concentration unit |
| Typical use | Material identification in chemistry and geology (mineral density tables) | Drinking-water quality standards and contaminant limits |
| Where it's used | Standard density unit in chemistry and materials science worldwide | The standard unit for drinking-water and environmental contaminant limits worldwide (EPA, WHO) |
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
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 milligrams per liter are in 1 gram per cubic centimeter?
1 gram per cubic centimeter equals 1,000,000 milligrams per liter, using the exact defined conversion factor rather than an estimate.
How do I convert gram per cubic centimeter to milligram per liter?
Multiply the gram per cubic centimeter value by 1000000. The converter above does this instantly to whatever precision you set.
How do I convert milligram per liter back to gram per cubic centimeter?
Use the reverse factor: 1 milligram per liter equals 0.000001 grams per cubic centimeter. You can also use the swap control in the converter above to flip the direction instantly.
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.
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.
Is the gram per cubic centimeter to milligram per liter conversion exact?
Yes. Both gram per cubic centimeter and milligram per liter are defined by fixed standards rather than physical artifacts, so the factor of 1000000 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 gram per cubic centimeter still used today?
Standard density unit in chemistry and materials science worldwide
