0.1 uM to microliters - (Sep/26/2012 )
trof and el crazy xabi, although the intent of my post was to point out that the m should not be capitalized, you are correct that it should be umol, not um.
it's nice to find out that i was part right about why L is used (so that l and 1 aren't confused) since it was a guess on my part (sounded good, though, and is true about older typewriters). i normally use l but used L in my earlier post to be consistent with the earlier posts.
It's about time people all over the world just burried typewriters. What evil comes from them.. capital L, qwertz keyboard in my country.. I'm sure there are more..
