As we know One μmol/L is equal to 0.001 mol/m³ (1 μmol/L = 0.001 mol/m³).

To convert Micromole/Liter to Mole/Cubic Meter, multiply your μmol/L figure by 0.001.

Example : convert 25 μmol/L to mol/m³:

25 μmol/L = 25 × 0.001 mol/m³ = mol/m³

To convert Mole/Cubic Meter to Micromole/Liter, divide your mol/m³ figure by 0.001.

Example : convert 25 mol/m³ to μmol/L:

25 mol/m³ = 25 ÷ 0.001 μmol/L = μmol/L
