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.

You need to know the flat projected area of your roof (the horizontal area from which it receives rain)
10 mm of rain is also 0.01 m. This falling on a 1 m² area is 0.01 m³ (or 10 L). Multiply by area of roof for total rain.
(NOTE: This would be MUCH more complicated using Imperial or US Customary units: how many gallons would be collected if 1/2 inch of rain falls on a roof 1 chain long by 2 poles wide? :shock: )
