expression _ ¡ tempUnit2
Converts a temperature value specified by
expression1
temperature units are:
_¡C
_¡F
_¡K
_¡R
For ¡, press 2 ".
TI-89: For _ , press ¥ .
TI-92 Plus: For _ , press 2 .
For example, 100_¡C converts to 212_¡F:

@tmpCnv(expression1_ ¡ tempUnit1, _ ¡ tempUnit2)
expression _ ¡ tempUnit2
Converts a temperature range (the difference
between two temperature values) specified
by
expression1
temperature units are:
_¡C
_¡F
_¡K
_¡R
For ¡, press 2 ".
TI-89: For _ , press ¥ .
TI-92 Plus: For _ , press 2 .
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:
0
