Converts a temperature value specified by
expression1
from one unit to another. Valid
temperature units are:
_
¡C
Celsius
_
¡F
Fahrenheit
_
¡K
Kelvin
_
¡R
Rankine
For example, 100_
¡C converts to 212_¡F:
To convert a temperature range, use

¡tempUnit2
Converts a temperature range (the difference
between two temperature values) specified
by
expression1
from one unit to another. Valid
temperature units are:
_
¡C
Celsius
_
¡F
Fahrenheit
_
¡K
Kelvin

1_
¡C and 1_¡K have the same magnitude, as
do 1_
¡F and 1_¡R. However, 1_¡C is 9/5 as
large as 1_
¡F.

For example, a 100_
¡C range (from 0_¡C to
100_
¡C) is equivalent to a 180_¡F range:
To convert a particular temperature value
