How to Read an Rpm Gauge
- 1). Look at your rpm gauge and notice that it is composed of a needle and ascending numbers from left to right. The needle moves as the rpm change to indicate the current speed of your engine.
- 2). Inspect your rpm gauge to see if it has been scaled down. For example, most rpm gauges in cars will say something along the lines of "RPM x1,000."
- 3). Multiply the number indicated by your rpm gauge needle with the proper scale if necessary. If your scale was 1,000 and your needle pointed at the number 3 on your gauge, then your total rpm would be 3,000.
