Hello,
Sorry to join this discussion so late, but I get the digest version of
Phys-L (and don't read them until days later, even so). I appologize if my
point has already been made
Did someone say:
"Since the number 0 doesn't need units for anything, why try to use them?"
I think that it is pretty important to include the units in stating the
value of a temperature, even if the value is zero (e.g. 0 degrees Celsius)
I don't think any of us would have it any other way.
Obviously this is a problem with temperature (and any other quantities?)
since the value of zero on the Celsius and Fahrenheit scales are based on
an arbitrary temperature. Those zero values of temperature do not coincide
and do not represent an "absolute" temperature value.
