Science Converter
Convert molarity or mole amount across common laboratory scales using one focused science converter.
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.
Molarity Converter
Enter a concentration and choose its starting unit. The table shows the same concentration across the full molarity scale as a quick sanity check. Scientific notation such as 1e-6 is supported.
| Unit | Symbol | Equivalence | Value | Amount in 1 µL |
|---|---|---|---|---|
| molar | M | 1 M | 1e-6 | |
| millimolar | mM | 10⁻³ M | 0.001 | |
| micromolar | µM | 10⁻⁶ M | 1 | 1 pmol |
| nanomolar | nM | 10⁻⁹ M | 1000 | |
| picomolar | pM | 10⁻¹² M | 1e6 | |
| femtomolar | fM | 10⁻¹⁵ M | 1e9 | |
| attomolar | aM | 10⁻¹⁸ M | 1e12 |
Concentration and chemical amount conversions
Choose Molarity or Mole Amount from the converter-type menu. Molarity describes concentration in moles per liter, while mole amount describes the quantity of substance.
Common scale checks
One micromolar equals 1,000 nanomolar. One micromole also equals 1,000 nanomoles, but these values describe different physical quantities and should not be used interchangeably.
