Conversion Calculator uses a calculator type interface to convert between various different units of measurement.  Currently, version 3.0 of the program supports about 1200 converions.  The program is Freeware.  It is a simple executable, and no installer is required.  It does not change the windows registry and makes no changes to your system files, and so to 'uninstall' the program simply delete it from your drive.  If you would like a link on the Start Menu to use in starting the program, please read the HTML page explaining how to go about this, included in this zip file.

Version 3.0 incorporates an automatic update feature.  The program can be expanded with new conversions by pressing the Update button, or by editing a simple Update.txt text file with Notepad to add the new conversions.  

The format for this text file is as follows

Leaps to Jumps,2.657

Where leaps is the 'Convert From' quantity, Jumps is the quantity that is being converted to, and the number after the comma is the ratio.  Most conversions are ratios, and the few that are not must still be hard coded in software.  The format shown above must be followed exactly or the program will remove the line from the text file and store it in another text file called 'error.txt'.  Duplicate entries will also be removed and stored in a file called 'Duplicate.txt'.  You can edit these files and then copy and paste the corrections into the Update.txt file.  All these text files will be found next to the program itself in the program's folder.  If you download an update.txt file or get one from someone else who is also using this program, you should remember not to paste the program on top of any updates you may have already created or you will overwrite and lose your updates.  Add these new conversions using Notepad and the copy and paste technique.  If you enter a value for one of the values already existing in the program your new value will be substituted when the program runs, overriding the hard coded conversion value for one of these 1200 values.

Please put something clear in the subject line of the email, such as 'Conversion Calculator etc'   I am confronted with hundreds of pieces of spam, as most people are, and an obscure heading on your email is likely to get it dumped into the trash can unread (I have noticed lately that spammers are experimenting with enticing headers on their emails like 'Hi Its me again' so don't put something like that as the subject line of the email.)

If a possible conversion does not exist directly on the interface, it is possible to make the conversion in a series of steps using the MOVE Button.  For example  Milligrams to Grains (MOVE) Grains to Ounces (MOVE) and then Ounces to Pounds.  Note that if you move repeatedly you might want to increase the right hand precision (set to a default of 4) to reduce accumulated rounding errors. If the quantity on the right is not available as a Convert From quantity the move button will not be able to locate it on the list of converions (which means that another route to the end destination must be found).
