26 ug/cubic meter to g/L

26 ug/cubic meter to g/L   (05/17/2007, 10:13 AM)

I have to convert the VOC emissions which are 26 ug/cubic meters to g/L for a submital sheet for a product used for a LEEDs project.
I hope someone can help me with this ASAP as I need it "yesterday" for work.
A big THANK YOU to whomever can provide me with an answer.
