The Ultimate Conversion Calculator version 3.0 for TI-83 Plus

By Jeffrey Hill

Directions

(skip to Example 1 or Example 2)

  1. Enter the number of units you would like to convert from.

  2. Find the unit of measure you want to convert from. If the unit of measure is not on the menu you are currently on, choose "PREVIOUS" to go to the previous menu or "NEXT" to go to the next menu. Units are listed in alphabetical order. Multi-dimensional units (i.e. square centimeters) will be in a submenu under the base unit (in this case, cm). If you are converting from a multi-dimensional unit (square centimeters, cubic feet, etc.), after choosing the base unit (centimeters, feet, etc.), a submenu will appear, asking you for the dimension you want to convert from. If measuring length (one dimension), choose the first unit. If measuring area (two dimensions), choose the second unit. If measuring volume (three dimensions), choose the third unit. To convert from 17 square centimeters to square inches, you would choose CM, then CM2.

  3. After selecting the source unit, a similar menu will appear, instead asking you for the unit to convert to.

  4. The program will then calculate the conversion. If the conversion is not possible (for example, °C to FT), it will tell you so and then send you back to the first screen (asking you for the value of the "from" unit.)

  5. If the conversion is possible, it will convert the value and show a screen similar to this example:

    24
    LBS.
    =
    10.88616
    KG

  6. Hit enter to go to the exit menu:
    CONVERT NEW will basically restart the conversion program, asking for a new value.
    CONVERT SAME will automatically use the same "from" value and unit to convert it to a different unit (for example, instead of 24 lbs. to kg, 24 lbs. to another weight unit).
    CONVERT RESULT will use the result conversion to convert to another unit (for example, it will take the result of 24 lbs. to kg and convert the kg value to another weight unit).
    EXIT will end the program.

Example 1

Problem: Convert 35 centimeters to inches
Step Example
Enter the number of units you would like to convert from. Type 35 and hit enter
Find the unit of measure you want to convert from. choose CM, then CM again
Choose unit of measure you want to convert to. choose IN, then IN again (you have to choose Next to go to the next screen first)
Program will calculate the conversion It is possible.
Value will be displayed 35
CM
=
13.77952756
IN.
Exit Menu Is Displayed Convert New = Go back to step 1 and do completely different conversion
Convert Same = Go back to step 3 and choose different "to" unit
Convert Result = Changes Result to the "from" value and choose a new "to" unit
Exit = Exits the program.

Example 2

Problem: Convert 76 square miles to square kilometers
Step Example
Enter the number of units you would like to convert from. Type 76 and hit enter
Find the unit of measure you want to convert from. choose MI., then MI.2 (you have to choose Next a couple of times to find MI.)
Choose unit of measure you want to convert to. choose KM, then KM2 (you have to choose Next first to find KM.)
Program will calculate the conversion It is possible.
Value will be displayed 76
MI2
=
196.8390964
KM2
Exit Menu Is Displayed Convert New = Go back to step 1 and do completely different conversion
Convert Same = Go back to step 3 and choose different "to" unit
Convert Result = Changes Result to the "from" value and choose a new "to" unit
Exit = Exits the program.

Updates to be included in Version 4:

Acres added to main program
Physics sub-program with rate, force, power, torque, pressure, and more.

This program should feature "double-conversion".  For a rate, you can convert from any distance unit to another, then convert the time unit to another!   Instead of settling for the standard mph, kph, ft/sec, and m/sec, you can find mm/min and more!

Check ticalc.org soon for Version 4!  I hope to get it up by early December 2002.
