Generally, you should shift gears up when the tachometer is around “3” or 3,000 RPMs; shift down when the tachometer is around “1” or 1,000 RPMs. After some experience with driving a stick shift, you’ll be able to figure out when to shift by the way your engine sounds and “feels.” More on that below.

How do you calculate RPM to mph?

Convert the Rotational Speed to MPH For example, if the rotational speed is 100 rpm, enter “× 100.” This gives you a value for feet traveled per hour based on the rotational speed and the circumference of the wheel. Multiply this number by 60 to convert it from feet per minute to feet per hour.

What speed is 1000 rpm?
