hi,
im having difficulty understanding the conversion from ppbv to ug/m3.
I know the answer is
(µg/ m3 * 24.45) /molecular weight of compound = ppbv
but when i use the ideal gas law PV=nRT, and i calculate for g/V, i get the units to equal g/L, and then to get ug/m3 i multiply my answer by
1 000 000 000. But the answer i get before i multiply by 1billion is the correct answer. Can someone please tell me why im not supposed to multiply my answer by 1billion?
thanks!!

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.

Hello, this value means the constant of gases, you do not need to transform your units.
