Need suggestions for a new project...

[IveBeenBad]

I have taken on the task of adding programming ti my list of skills, and while thinking about a good way to get started, I thought about ideas for a program to start with. I thought for a while over some chalupas, and came to a conclusion. Cars.

What I would like to do is gather up a list of automotive calculations and conversions and then make a program to figure these things out for you. I am asking that members submit any calculations and conversion they see useful along with the formula (if known).

Thanks in advance and hopefully this project will be one I remember for a while!
