3) Can you send me an Excel spreadsheet with these calculations?

No, I have only created the calculators as Javascripts, so either use them as Javascripts, or go to the pages of calculator equations (as described in items 1 and 2 above) and write your own spreadsheet program using the equations and algorithms that I've described.
 

4) Can I use the calculator when I'm not connected to the internet?

Sure... it's very easy to save the calculator on your computer. In fact, virtually any web page from any web site can be saved on your computer.
 
If, for example, you are using Microsoft Internet Explorer, just go to the web page that you want to save.. then in the web browser menu bar, click on File, then click on Save As.

A Save Web Page dialog box will then pop open... Choose a file name and location that suit you, select Save as type Web Page Complete, and Encoding Western European (Windows).. then click Save.

Presto.. the web page is now stored on your computer and can be run anywhere, anytime.

5) Can I put the calculators on another web site?

No... Please don't. From time to time I make changes and improvements in the calculators, and I want all users to be able to come to this web site in order to use the very latest, most accurate versions of these copyrighted calculators.

As alternatives to putting my calculators on your web site: you can open a new browser window and display my web page in that new window, or you can just give your users a link to my web page.
