Over the years I've evolved a speed calculator Excel spreadsheet that's fairly useful. The basic formula is pretty simple and known to most of us that choose to get into any kind of calculations. The evolution here has been in the formating. It's attached for anyone to use as he see's fit. You can even package it, change it and sell it if you want without any further OK's from me. It's free!!
It's attached in a 68KB file.
If you have any trouble loading or using it email me, It should load in most simpler (cheaper) spreadsheet programs. But if it doesn't I can save it in a variety of other formats for older programs.
