Conduit and Trough Fill Excel Spread Sheet
This spread sheet will calculate fill for conduit and trough.

It seems there is still a demand for a tool to help in conduit fill calculation.  So I thought that an Excel spread sheet would be appreciated.  It is a little confusing at first, but it will make sense after you play with it.
 
If you have any questions, feel free to email me.  The download is free and you can redistribute it.  All I ask is that you don't change it, or take credit for it's creation.

Thanks to Toby Grotz; the spread sheet was updated to include cables.  He can be reached at wireless2@mindspring.com
