Questions and answers on how to convert things from one unit or system to another
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 pageThank you for being with us and sorry for any inconveniences this could caused.

Hello,
in an abstract I found teh Unit pM. What for an Unit is this? What is pM for an abbreviation?
Thanks

Picomolar? The molarity of a solution is the number of moles of a substance in liter of solution. 1 M NaCl would be 1 mole of NaCl dissolved in enough water that the total volume of solution would be 1 L
In the SI, molarity, molality, and normality are considered obsolete and not recommended. NIST SP 811 recommends mol/L or mol/dm^3 to replace M for molarity. I believe ISO 31-8 is consistent with SP811. However, I still see a ton of chemistry references to these three terms on the web.
A 1 pM solution would be very dilute, 1 picomole per liter of solution.
