Micromolar to PPM Formula
The conversion from micromolar to ppm depends on the molar mass of the substance:
ppm=μM×Molar Mass (g/mol)×10 −3
Where:
- μM is micromolar (µmol/L)
- Molar Mass is in g/mol
- ppm is in mg/L (for aqueous solutions)
For example:
- 1 μM of glucose (180.16 g/mol) →
1×180.16×10−3 =0.18016 ppm
Micromolar to PPM Conversions
| Micromolar (μM) | Molar Mass (g/mol) | Result (ppm) |
|---|---|---|
| 1 μM | 180.16 | 0.1802 |
| 10 μM | 180.16 | 1.8016 |
| 50 μM | 46.07 (Ethanol) | 2.3035 |
| 100 μM | 18.02 (Water) | 1.802 |
| 1000 μM | 100 | 100.00 |
Note: These conversions are valid for aqueous solutions where the density is approximately 1 g/mL.

FAQs
1. Is micromolar the same as ppm?
No. Micromolar (μM) is a measure of the number of molecules (µmol/L), while ppm is a measure of mass (mg/L). You need to know the molar mass to convert between them.
2. What molar mass should I use?
Use the molecular weight of the compound you're measuring. For example:
- Glucose: 180.16 g/mol
- Ethanol: 46.07 g/mol
- Water: 18.02 g/mol
3. Does temperature or solvent affect this?
Yes. This formula assumes the solvent is water at 25°C with a density of 1 g/mL. Different solvents or densities can slightly affect the ppm result.
