Linear Taper Potentiometer

I have been working on a project that uses a pot as a steering wheel. My first attempt caused me to learn that some potentiometers taper, increasing the amount of resistance towards the end of travel, rather than apply equal resistance per amount the dial is turned. I went back to the shack today to buy a non-tapering pot to learn that they didn't have any in the style switch I needed. So, my question is this.... What is the formula I need to use to convert the amount of resistance to a physical dial position (say 45 degrees right of center)?

This is a good link on converting LOG pots to linear:-

good stuf very clearly explained
he deserves a karma+ for that!

VERY cool Grumpy_Mike!!!! Thank you. Sorry it took me so long to show my appreciation. We had a day and a half of freezing rain which followed with a day and a half without internet!
