Sum*****! You're right!

From now on, I'm using N m for all my measurements!

Since we are getting all scientific I will point out that a Watt is a Joule/Second.

Power = Energy/Time

Wrong! A Joule is a unit of energy.

Wrong again! Energy/Time is Power (ie Joule/Sec = Watts).

Learn about it and then come at me with something better than a 'yo momma' joke. :rolleyes:

Kenhill, that's Newton-Meters. N-M. Nm is a terribly small measure of distance.

Nm is newton metres
nm is nanometres
A lower case for a proper noun for a unit spelt out eg newton, joule , upper case for N, J
