That would be Nm as in (N)(m), Newton x Meters.  Or
(Kg)(m^2)/(second^2).

Are you referring to a 24 hour clock where 1200 hours=12pm(noon) and
2400hours=12am(midnight)
Therefore 1400 hours= 2pm(in the afternoon)

Sound intensity is measured in (Watts)/(meters^2) and in decibels.
The scale for sound intensity is logarithmic and is expressed by the
equation:  B(Beta)(in dB)=10logI/Io
I=intensity
Io=intensity of some reference level

You can think of Watts  being equal to J/sec.= 3.42 Btu/h
=0.738(ft)(lb)/sec



A question of my own.  WHen converting mmHg to inHg is it simply
converting mm to inches?
