: Dear Superdave The Wonderchemist

:         Would dynes/cm be some sort of ancient measurement?
:         
:         Does it have any relationship to Newtons/metre????

: p.s celcius ... Superspelling of celsius, I presume :)

celcius is the correct spelling of celsius after 12:00 AM CST.  One 
Newton/m is equal to 100 dynes/cm IIRC.
