As we know One mol/dm³ is equal to 0.001 kmol/L (1 mol/dm³ = 0.001 kmol/L).

To convert Mole/Cubic Decimeter to Kilomole/Liter, multiply your mol/dm³ figure by 0.001.

Example : convert 25 mol/dm³ to kmol/L:

25 mol/dm³ = 25 × 0.001 kmol/L = kmol/L

To convert Kilomole/Liter to Mole/Cubic Decimeter, divide your kmol/L figure by 0.001.

Example : convert 25 kmol/L to mol/dm³:

25 kmol/L = 25 ÷ 0.001 mol/dm³ = mol/dm³
