Mole Converter
Convert amount of substance between mol, mmol, µmol, nmol, pmol, fmol, and amol laboratory scales.
This calculator is useful when you need a quick unit check without working through each conversion factor by hand. Enter one value to compare every supported unit side by side.
Mole Converter
Enter a mole amount and choose its starting unit. The table converts the same amount across mol, mmol, µmol, nmol, pmol, fmol, and amol.
| Unit | Symbol | Equivalence | Value |
|---|---|---|---|
| mole | mol | 1 mol | 1e-6 |
| millimole | mmol | 10⁻³ mol | 0.001 |
| micromole | µmol | 10⁻⁶ mol | 1 |
| nanomole | nmol | 10⁻⁹ mol | 1000 |
| picomole | pmol | 10⁻¹² mol | 1e6 |
| femtomole | fmol | 10⁻¹⁵ mol | 1e9 |
| attomole | amol | 10⁻¹⁸ mol | 1e12 |
Mole conversions across laboratory scales
This converter is useful when protocols, samples, or experimental results report the same amount of substance using different metric prefixes.
What a mole measures
The mole is the SI unit for amount of substance. Unlike molarity, a mole amount does not describe concentration because it does not include the solution volume.
Example
Enter 1 µmol to see that it equals 1,000 nmol or 1e6 pmol.
