Mg To Ml (Fabiana Is Kind Of Wrong)

posted by Chike T. on 26 May 2010 at 9:57 am

Hello my dearest Fabiana, l really do not mean any disrespect but l'm going to have to say that you're wrong with the conversion you did on "converting from mg to ml."

Before you do such conversions, you're going to, first of all, make sure both units are similar. And in this case, i.e., from mg to ml, they are not so there is no such way to convert these kind of units.

These are two different units on their own, so converting them the way you did (1g = 1000mg = 1ml) is not so right. But (1g = 1000mg) however, is right...the later, is not. Thank you! Good job though!

May Help...

1 ml is 1/1000 of a liter, which is a volume. 1 mg is 1/1000 of a gram which is a weight. So they are not convertible.

Actually, to be more accurate, they can be converted using the following information:
1 liter of pure water equals 1 kg (kilogram). So, if you are trying to convert a liquid similar to water, an approximation can be achieved with: 1ml = .001mg (1 ml is 1/1000 liter; 1 mg is 1/1000000 kg).
In this case, if the medicine in similar to water in weight, it would be approximately 100 mg=0.1ml

Editor note: The Calculator Site has a weight to volume calculator tool ( to help you with your conversion.

Apples To Oranges... Simple Really

posted by Chris on 03 January 2011 at 4:19 pm

The concept is actually pretty simple - to answer any of these questions you need one piece of additional information:

How many mg are there per ml of stuff you're measuring?

Every single drug ever made that is in liquid form MUST list the "concentration" of the liquid in question.... some drugs even have multiple forms with multiple concentrations. Much like not everyone likes a lot of sugar in their coffee, not all drugs have the same amount of drug per milliliter, cup, or whatever unit you're asking about. Each drug company makes their drugs in standard concentrations and these can be found on any container labeled appropriately for the particular drug in question - in fact, pharmacies that dispense meds are REQUIRED to have this info on the label.

Example - most diphenhydramine (Benadryl) liquid comes in a concentration of 12.5mg per teaspoon (1 tsp = 5ml). So if someone wants 50mg, they need 4 tsp or 20ml.
