We have currently covered all the basics of programming, but still have lots left to learn. All of the stuff you learn from here is your own perseverance to learn more. We will however shortly create a database, which is definitely in the more advanced realm of programming. On this page, you are given the opportunity to make a conversion program. If you really have no interest, I suggest you download the zip files. However, this program does show the importance of writing comments in your own coding. But hey, at least YOU do not have to search for all the conversion factors for this program. I have already found the ones I want to use. By the way, I could never keep my sanity to give directions to make a program like this. This is also your opportunity to do something on your own if you wish to. I am stopping after the tables. I have given you a link to the completed program which is zipped at the bottom of this page. So if you want to try this program, see the tables below:
Conversion Factors for Area
| To convert from | To | Multiply by | Conversely, divide by |
| Acres | Square Centimeters | 40,469,000 | 40,469,000 |
| Acres | Square Feet | 43,560 | 43,560 |
| Acres | Square Meters | 4,047 | 4,047 |
| Acres | Square Miles | 640 (Divide) | 640 (Multiply) |
| Square Miles | Square Meters | 2,591,314.38 | 2,591,314.38 |
| Square Miles | Square Feet | 27,878,400 | 27,878,400 |
| Square Miles | Square Centimeters | 25,899,881,103 | 25,899,881,103 |
| Square Meters | Square Feet | 10.76 | 10.76 |
| Square Meters | Square Centimeters | 10,000 | 10,000 |
| Square Feet | Square Centimeters | 929 | 929 |
Be sure to notice that Acres to Square Miles divides and multiplies conversely (obviously). I use divide because it is obnoxious to show such bizarre decimals. For instance, there are approximately .00002296 acres in one square foot. It looks much better in coding just to divide the amount of square feet by the amount of square feet given by the amount of square feet in an acre (43,560).

So the idea of this is just to have fun. I would put all of the units in a list box. Then I would have six option buttons (one for each different conversion type), which should clear the list boxes and add the new items. I would use six different functions, testing every single possible condition (I could never remain sane if I had to write all this out!). You should test the conditions with the ListIndex property (the selected item) of the list box.
**Note: In case you are not aware, if the conversion factor says to divide, but you prefer to multiply, enter that value into the calculator in windows, then press the 1/X button. You should multiply by that value if you prefer, because that value is the reciprocal. You can press 1/X when the factor says to multiply and you prefer to divide as well.**
Congratulations, you have made it through! I hope you are comfortable using Visual Basic by now. The next section is the advanced section. Now you may proceed there --> Continue.
