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.

For a UV cleaning device design I need to know how to convert J/m² to mW/cm².
Thanks

You can't quite do that as watts are power and joules are energy. A joule is a watt*second.
1 mW/cm^2 = 1 x 10^(-3) W/ 1 x 10^(-4) m^2 = 10 W/m^2
You will then have to look at how many seconds of exposure to get to J/m^2.
