I read a thread asking about converting litres to gallons or ounces and thought I would share this conversion program I have had for years. I've always defaulted back to using it as I think it's one of the better ones you'll find. I don't own any sort of copyright on it and it says in the "About" that it is free to share and distribute. It is an .exe file so I uploaded it as a .zip file. Let me know if that works for any of you.
EDIT: Ok, couldn't figure out how to attach an .exe or .zip file without it turning into attachment.php, whatever that is.
So here's the developer's website link instead: http://joshmadison.com/convert-for-windows/
