About Converting Milligrams per Milliliter to Grams per Cubic Centimeter
Milligram per Milliliter 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. Both are mass per volume density units.
Formula
grams per cubic centimeter = milligrams per milliliter × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per milliliter equals 1 base unit, and 1 gram per cubic centimeter equals 1000 base units, so dividing one by the other gives the direct milligram per milliliter-to-gram per cubic centimeter factor of 0.001.
Simple example
1 mg/mL × 0.001 = 0.001 g/cm3
1 milligram per milliliter = 0.001 grams per cubic centimeter.
Real-world example
1,000 mg/mL × 0.001 = 1 g/cm3
1,000 milligrams per milliliter = 1 grams per cubic centimeter.
Conversion table
| Milligram per Milliliter (mg/mL) | Gram per Cubic Centimeter (g/cm3) |
|---|---|
| 0.1 mg/mL | 0.0001 g/cm3 |
| 1 mg/mL | 0.001 g/cm3 |
| 10 mg/mL | 0.01 g/cm3 |
| 100 mg/mL | 0.1 g/cm3 |
| 1,000 mg/mL | 1 g/cm3 |
| 10,000 mg/mL | 10 g/cm3 |
Reverse conversion: Gram per Cubic Centimeter to Milligram per Milliliter
0.001 g/cm3 × 1000 = 1 mg/mL
0.001 grams per cubic centimeter = 1 milligrams per milliliter.
milligrams per milliliter = grams per cubic centimeter × 1000

Frequently asked questions
How many grams per cubic centimeter are in 1 milligram per milliliter?
1 milligram per milliliter equals 0.001 grams per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert milligram per milliliter to gram per cubic centimeter?
Multiply the milligram per milliliter value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert gram per cubic centimeter back to milligram per milliliter?
Use the reverse factor: 1 gram per cubic centimeter equals 1,000 milligrams per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a milligram per milliliter?
Milligram per Milliliter (mg/mL) is a unit of density.
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 milliliter to gram per cubic centimeter conversion exact?
Yes. Both milligram per milliliter and gram per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.001 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.
