Petahertz (phz) to Cycles per Minute (cpm) Converter

What is Frequency?

Frequency refers to the number of occurrences of a repeating event per unit of time. It is measured in Hertz (Hz), which equals one cycle per second. Other frequency units include kHz (Kilohertz), MHz (Megahertz), and RPM (Revolutions per Minute).

Common frequency units

• Hertz (Hz): The standard unit of frequency, equal to one cycle per second.
• Kilohertz (kHz): 1,000 Hertz.
• Megahertz (MHz): 1,000 Kilohertz or 1,000,000 Hertz.
• Gigahertz (GHz): 1,000 MHz or 1 billion Hertz.
• RPM: Revolutions per minute, commonly used for rotational frequencies in machines.

How to convert frequency units?

To convert frequency units, you multiply or divide based on their relative scale. For instance, to convert kHz to Hz, multiply the value by 1,000. Similarly, to convert Hz to MHz, divide the value by 1,000,000.

Applications of frequency conversions

• Audio engineering: Converting frequencies between Hertz and Kilohertz for sound wave analysis.
• Networking: Understanding bandwidth in Megahertz or Gigahertz.
• Physics: Measuring and converting electromagnetic wave frequencies.

What is Hertz used for?

Hertz is widely used in multiple fields such as audio frequencies (e.g., 20 Hz to 20 kHz, the range of human hearing), radio waves (e.g., FM radio operates around 88-108 MHz), and electricity (e.g., 50/60 Hz for alternating current).

How do RPM and Hz relate?

Revolutions per Minute (RPM) is commonly converted to Hertz for rotational motion. Since 1 Hz = 60 RPM, you divide RPM by 60 to get the frequency in Hertz.

Why do we use Kilohertz, Megahertz, and Gigahertz?

These units simplify the representation of large values. For example, instead of saying 1,000,000 Hz, you can use 1 MHz. This is particularly useful in fields like communication and computing, where frequencies often reach the GHz range.

How do electromagnetic waves relate to frequency?

Electromagnetic waves, such as light or radio waves, have frequencies that define their energy. For instance, visible light has frequencies between 400 THz and 800 THz, while radio waves range from 3 kHz to 300 GHz.

What is the range of human hearing in frequency?

Humans can typically hear frequencies between 20 Hz and 20,000 Hz (20 kHz). Frequencies above this range are referred to as ultrasound and those below are known as infrasound.

What are terahertz and their applications?

Terahertz (THz) frequencies are used in advanced applications like spectroscopy, medical imaging, and high-speed wireless communication. For instance, THz waves can penetrate materials like plastics and wood, enabling non-destructive testing.

How to calculate wavelength from frequency?

The wavelength of a wave is calculated using the formula wavelength = speed of light / frequency. For example, a wave with a frequency of 100 MHz has a wavelength of approximately 3 meters.
