Dear convert-me.com forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

How do you convert from micrograms/cubic centimetre to mol/litre? I've got 40 micrograms/cubic centimetre of iron solution and need to convert to its equivalent volume in mol/litre.

To figure this out, you need to know the atomic weight of Iron. A trip to your periodic chart will give you an answer of 55.85 grams per mole.

If you have a solution of iron at 40 µg/ml, then we can convert thusly:

40 µg / 55.85 g/mol =
0.00004 g / 55.85 g/mol = 7.16e-7 mol = .716 µmol

to convert ml to liters we'll use 1 ml = 0.001 l so:

.716 µmol / 0.001 l = 716 µmol/l
