A mole (mol) is the SI unit for amount of substance, while a millimole (mmol) is one-thousandth of a mole. These units are commonly used in chemistry and biochemistry to measure the amount of substances in reactions and solutions.
| Millimoles (mmol) | Moles (mol) |
|---|---|
| 1 mmol | 0.001 mol |
| 10 mmol | 0.01 mol |
| 100 mmol | 0.1 mol |
| 1000 mmol | 1 mol |
To convert millimoles (mmol) to moles (mol), divide the number of millimoles by 1000:
Formula: mol = mmol ÷ 1000
Example: Convert 500 mmol to mol
500 mmol = 500 ÷ 1000 = 0.5 mol
To convert moles (mol) to millimoles (mmol), multiply the number of moles by 1000:
Formula: mmol = mol × 1000
Example: Convert 0.25 mol to mmol
0.25 mol = 0.25 × 1000 = 250 mmol
