Forum rules
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.

The "M" used to be used to represent molarity, the number of moles of a substance per liter of solution, so molarity per liter doesn't really make sense. The term is deprecated now but moles/liter is OK.

I'm sure it means a 4.5 millimolar solution, that is 4.5 mmol per liter of solution, but that should be written 4.5 mmol/L.

The small "m" was used for molality, 1 mole per kilogram of solvent, but obviously could be confused with meter.
