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.

Atmospheric air is 21% oxygen.
But if you breathe in and exhale, the exhaled air is less than 21% O2, as you use some and exhale more CO2. Sorry but I have no idea of the percentage. Probably only a couple of percent reduction.
If you blow the balloon up from a compressor, 21%.

Thanks - maybe I'll compute using 21%...its one step closer than I was.
:D
