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
@tmpCnv() instead.
tmpCnv(100_¡c,_¡f) ¸212.ø_¡F
tmpCnv(32_¡f,_¡c) ¸0.ø_¡C
tmpCnv(0_¡c,_¡k) ¸273.15ø_¡K
tmpCnv(0_¡f,_¡r) ¸459.67ø_¡R

@tmpCnv(expression1_

⇒ 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.
To get @, you can press ¥ c ¤ [D]
(or 2¿

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
instead of a range, use tmpCnv().
