What speed at X RPM?

[jackb]

Does anybody have a chart or way of relatively accurate way of knowing what speed you are traveling based on RPM/gear after the speedometer pegs?
In 5th gear, I hit 85mpg ~3,000rpm. How fast am I going at 3,500rpm? 4,000rpm? I don't own a gps that measures speed to find out.

If you have an iPhone or Android, you can download a speedometer app.
