Conversion formula

mmol = amol × 1e-15

One attomole equals 1e-15 millimole. Multiply your value in attomole by this factor to get millimole. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 attomole:
5 × 1e-15 = 5e-15 mmol

About these measurements

Amount of substance counts specified elementary entities in moles.

The base reference used here is the mole. One attomole is 1e-18 base units; one millimole is 0.001 base units.

Important distinctions

Always specify whether the entities are atoms, molecules, ions, or another defined type.

Precision

The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
