My car idles around 600 RPM which is equal to about 10 cycles per second and redlines at around 6,000 RPM which is 100 cycles per second. This just seems like a more friendly scale to use. I am curious why we use RPM instead of Hertz to measure engine speeds.
In: 1
1. Hertz is a measurement of frequency and can measure various actions. RPM is more specific to the action of an engine.
2. Hertz is usually in cycles per second. While it may be more specific, slight variations in cycles would require decimals to accurately convey changes and be less obvious. Ex: 6 vs 6.2 is less noticeable than 600 vs 620 cycles.
3. Just because.
