How to Convert Step by Step

Converting between litres and millilitres takes just a moment once you know the method.

  1. Identify your starting value – Note whether you have litres or millilitres
  2. Apply the conversion factor – Multiply by 1,000 (for l to ml) or divide by 1,000 (for ml to l)
  3. Check your decimal point – When multiplying by 1,000, move the decimal three places right
  4. Verify your answer – Millilitres should be a larger number than litres for the same volume

Example: Converting 2.3 litres to millilitres means multiplying 2.3 by 1,000, which equals 2,300 ml. You’re moving the decimal point three places to the right.
