To convert from megahertz (MHz) to radian per second (rad/s), use the following formula:
A megahertz (MHz) is a unit used to measure frequency, and it's equal to one million hertz (Hz).
Think of it as a way of counting how many times something happens per second. You'll encounter this measurement in various parts of modern technology, from your car radio to the computer on your desk.
Megahertz is the standard unit for measuring radio frequency, especially for FM (Frequency Modulation) radio.
When you tune your radio to a station like "98.7 FM," you're actually selecting a specific broadcast frequency of 98.7 megahertz.
Each station in the FM broadcast band (which typically spans 88 to 108 MHz) is assigned its own unique frequency.
This prevents signals from overlapping and interfering with each other, allowing your radio to isolate and play the desired station clearly.
In the world of computer processors (CPUs), it's a common misconception that a higher megahertz (MHz) or gigahertz (GHz) rating automatically means better processor performance.
This concept is often referred to as the "megahertz myth."
While clock speed (the rate at which a processor executes instructions, measured in MHz or GHz) is a part of the puzzle, it isn't everything.
A modern processor's overall speed and efficiency depend more on other key factors, such as:
Because of this, a newer processor with a lower clock speed but a more advanced design can easily outperform an older one with a higher clock speed.
The unit "hertz," and by extension megahertz, is named in honor of the German physicist Heinrich Hertz.
In the late 1880s, Hertz was the first person to definitively prove the existence of electromagnetic waves—something that had only been a theory until then.
His foundational work paved the way for nearly all modern wireless technology, including radio, television, and Wi-Fi. Naming the unit of frequency after him is a tribute to his groundbreaking discoveries.
