TI-89: Converting Temperatures

This is a response to Manny's question that he posted about a week ago, but may be useful to others. When converting temps, you can't just use the standard notation I discussed a couple weeks ago, because the calculator thinks the degrees sign is referring to an angle measure. You have to use the tmpCnv() function found in the catalog under T. The first argument is the "from" temp with value and units, the second argument is the "to" unit. Here's an example:
tmpCnv(32_°F,_°C)
= 0_°C
