So you have your PSP GPS attachment and a roadmap, and you also think you're ready to go on your extra special road trip. Before you do, you may want to try this little new app jay543_uk out. It's called the PSP Automotive Converter, and it does basic motoring calculations for the PSP enthusiast.

What calculations, you might ask? Well, the app can calculate for engine power, gas mileage, oil ratios, and even convert mph to kph. It's a nifty tool for car lovers who want to do some quick calculations and have a PSP handy.

jay543_uk notes, however, that it's still pretty new. He writes, "It is a little app which will work out some simple automotive conversions. Sorry if the code is all messed up, I am very new to all this and really just want some pointers on if I am doing stuff right or if I should just give up." Still, if you want to convert mph into kph or figure out how many miles you get per gallon of fuel you use, then why not give it a try?
