There is no unit called "mld". It's possible you meant one of the following:

* mL (milliliter): 1 milliliter (mL) is equal to 0.001 liters (L).

* MLD (Minimum Lethal Dose): MLD is a medical term and not a unit of volume. It refers to the smallest amount of a substance that is likely to cause death.

Please clarify what you meant by "mld" so I can give you the correct answer.
