Nano moles to micro grams or UG/L

Nano moles to micro grams or UG/L   (06/05/2011, 11:37 PM)

I have 47.2 ug/l of cobalt in my blood stream. It seems that in Australia they use the term nano moles as the measure of cobalt in blood. I was wondering how my levels of 47.2 ug/l compares of nano moles.
