Well if your wanting to do for temperatures on your ti 89 all you need to do is type tmpcnv( then 2nd 3
this will bring up your units and you want to go down to temperature
then , then 2nd 3 and pick what unit you want to converte the temp in to. then close)

so looks something like tmpCnv(_F,_C) which will convert fahrenheit to Celsius

if you want to you can also put a number in like tmpCnv(40_C,_F) and it will give you 104.00_F

hope that helps.

*btw there is a degree sign between _ and C but don't know how to put it on the computer

Hello,
K for Kelvin, C for Celsius, F for Fahrenheit
T in K =T in C + 273
T in F = 32 F + 9/5(T in C)
T in C = (5/9)*(T in F -32 F)
Hope it helps.

### How to convert Pressures on a TI-89?

The same way you convert any other units other than temperature, using the Units menu (2ND 3) and the -> operator (2ND MODE).

As an example, to convert 1.1 atmospheres to mm of mercury:

1.1 2ND 3 2ND Down Down Down Down Down  ENTER 2ND MODE 2ND 3 2ND Down Down Down Down Down Right Down Down Down Down Down ENTER ENTER

You should see 836. _mmHg

### I can't find this button on my calculator / this

A fraction is in fact a ratio of two number: a division of a numerator by a denominator. The key used for the division operation is the one above the multiplication sign and below the caret [^], and in thee rightmost column of keys.

Beware that this calculator converts any ratio of two numbers into a decimal value. To keep a fraction in a fraction form you must use the [|=>Frac] or [ToFrac] command. To convert a decimal result to a fraction, use the [|=>Dec] command.
These commands are accessible through the CATALOG or more easily by pressing [MATH] (under the ALPHA key) and selecting [1:|=>Frac], or [2:|=>Dec]
Ex: to keep 27/48 in fraction form you enter
27 [/] 48 [MATH][1:|=>Frac] [ENTER]. Result is 9/16
You will notice that the resulting fraction is reduced to its simplest form.
To convert the above result from fraction to decimal press [MATH][2:|=>Dec]

A fraction can always be approximated by a decimal value but the converse is not always possible.

### My TI-89 won't convert temperatures. It handles other types of conversions fine (like pressure _atm to _mmHg) but gives me a "Error: Inconsistent units" message even with _F to _C or _C to _F. What's...

Hi,
There is nothing wrong. For all units except temperatures you use the [|=>] the arrow operator to convert from one to anther. For temperature conversions however, you must use the tmpCnv( command.

Exemple of syntax. tmpCnv( is accessed through the catalaog or enter using the Alpha_shifted keys (Ti89)

tmpCnv( 100_ deg C,_ deg F) [ENTER] should give 212
You should explicitly enter the underscores, the degree symbols and the C, and F. The last two need not be capital letters).

Hope it helps.
