Simply put, rotations per minute (RPM) measures the speed at which something is spinning.
It counts the number of full turns an object completes in one minute. From car engines to computer hard drives, RPM is a key indicator of performance and speed.
The concept of RPM (rotations per minute) gained popularity during the Industrial Revolution, thanks in large part to Scottish engineer James Watt.
While developing his steam engine, Watt needed a way to compare its power output to that of a horse. To do this, he determined how many times a horse could turn a mill wheel in one minute.
He utilized this rotational measurement to help establish the definition of horsepower. As a result, RPM became a crucial metric for quantifying the performance and work capacity of mechanical engines—a practice that continues to this day.
You encounter RPM every day in common technology.
In your car, the tachometer displays the engine's speed in rotations per minute, indicating how fast the crankshaft is spinning. A higher RPM generally means more power is being produced.
Computer hard disk drives (HDDs) also use RPM to measure their performance; a 7200 RPM drive can read and write data faster than a 5400 RPM drive.
RPM ratings, which denote motor speed and efficiency, are also found on household appliances such as blenders, washing machines, and fans.
Although RPM is a common unit, physics and engineering often use hertz (Hz) for frequency and radians per second (rad/s) for angular velocity.
The conversion is straightforward:
To Hertz (Hz): Because a minute has 60 seconds, you divide the RPM value by 60.
To Radians per Second (rad/s): One complete rotation is equivalent to 2π radians. To convert RPM to radians per second, multiply the RPM value by 2π, then divide by 60.
A gigahertz (GHz) is a unit of frequency in the International System of Units (SI), equal to one billion hertz (109 Hz). The plural form is gigahertz.
The gigahertz measurement is famously used to indicate a computer's CPU clock speed, which tells you how many processing cycles it can complete per second.
For example, a 3.2 GHz processor can handle 3.2 billion cycles every second.
While a higher GHz number often suggests a faster processor, overall performance also depends on other critical factors, such as the number of cores and the chip's architecture.
Your daily wireless connections, like Wi-Fi and Bluetooth, operate on specific gigahertz frequency bands.
The most common Wi-Fi bands are 2.4 GHz and 5 GHz.
Each has its own strengths:
Similarly, 5G mobile networks use various GHz frequencies to deliver the ultra-fast data transmission that powers modern mobile devices.
Focusing solely on gigahertz to judge a processor's performance is a common mistake known as the "gigahertz myth."
A processor with a lower clock speed but a more efficient design (e.g., more cores, a larger cache, or better instructions per cycle) can easily outperform a processor with a higher GHz rating.
This is why comparing processors requires looking at a combination of specifications, not just the clock speed.
