How many ml is equal to 18mg - Office Equipment & Supplies

Depends what you are measuring. You need to repost with the material that you are measuring.

For example, 1 litre of water weighs 1 kilogram.

So, 1 litre of water weighs 1,000 grams.

Thus, 1,000 millilitres weighs 1,000 grams

So, 1 millilitre weighs 1 gram.

Thus, 18/1000 millilitres weighs 18/1000 grams.

I get 0.018 ml = 18 mg.

Good luck,

Paul
