How It Works
This converter works in 3 steps.
Enter the value
Type the number.
Choose its unit
Select g/L, mg/mL, mg/L, µg/mL, ng/mL, µg/L, g/dL, or mg/dL.
Read every unit
The converter scales by mass prefix and volume prefix and lists all results.
Check equal pairs
The converter marks unit pairs with identical values, such as mg/L and µg/mL.
The Formula
The formula multiplies the value by the ratio of mass prefix to volume prefix.
g/L = value × (mass factor / volume factor)1 g/L = 1 mg/mL; 1 mg/L = 1 µg/mL = 1,000 ng/mL1 g/dL = 10 g/L = 1% w/v- mass factor:
- g = 1, mg = 10⁻³, µg = 10⁻⁶, ng = 10⁻⁹
- volume factor:
- L = 1, dL = 0.1, mL = 10⁻³
A protein reading of 500 ng/mL equals 0.5 µg/mL, 0.5 mg/L, and 5 × 10⁻⁴ g/L.
Conversion Table
The conversion table shows 7 values in g/L, mg/L, µg/L, and g/dL.
| Value | g/L (= mg/mL) | mg/L (= µg/mL) | µg/L (= ng/mL) | g/dL (= % w/v) |
|---|---|---|---|---|
| 1 g/L | 1 | 1,000 | 1,000,000 | 0.1 |
| 1 mg/mL | 1 | 1,000 | 1,000,000 | 0.1 |
| 1 mg/L | 0.001 | 1 | 1,000 | 0.0001 |
| 1 µg/mL | 0.001 | 1 | 1,000 | 0.0001 |
| 500 ng/mL | 0.0005 | 0.5 | 500 | 5 × 10⁻⁵ |
| 25 µg/L | 2.5 × 10⁻⁵ | 0.025 | 25 | 2.5 × 10⁻⁶ |
| 2 g/dL | 20 | 20,000 | 20,000,000 | 2 |
What Is the Mass Concentration Unit Converter?
The Mass Concentration Unit Converter is a tool that converts between mass-per-volume units, including g/L, mg/mL, mg/L, µg/mL, ng/mL, µg/L, g/dL, and mg/dL. Several pairs are equal by definition: 1 g/L = 1 mg/mL, and 1 mg/L = 1 µg/mL.
Clinical labs report many analytes in mg/dL or g/dL, while research labs use mg/mL and µg/mL. The converter lists all forms together and adds % w/v, which equals g/dL. No molecular weight is needed, since all units share the mass-per-volume family.
Common Uses
There are 5 main uses of this converter.
Clinical reporting
Lab staff convert g/dL hemoglobin and mg/dL glucose to SI-style units.
Protein work
Biochemists convert µg/mL readings to mg/mL stocks.
Environmental data
Analysts convert µg/L results to mg/L for permit reports.
Drug dosing solutions
Pharmacists check mg/mL and µg/mL labels.
