expression _¡tempUnit2
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:

expression _¡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
_¡R Rankine
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.
