Frequency Converter
Convert frequency between Hz, kHz, MHz, GHz, rad/s, RPM, and cps instantly.
The Frequency Converter converts between hertz, kilohertz, megahertz, gigahertz, radians per second, RPM, and cycles per second. It is a quick reference for signal, audio, and electronics work.
What is a Frequency Converter?
A frequency converter is a tool that translates measurements of how often something occurs within a given time period, typically measured in hertz (Hz) or other related units. Frequency is a fundamental concept in physics, engineering, electronics, and many scientific disciplines. It describes the number of cycles or events that occur per second, making it essential for understanding wave behavior, electrical signals, rotational motion, and numerous other phenomena where periodicity plays a role in signal processing, communication systems, timing applications, audio engineering, and numerous other technical fields that rely on accurate time and frequency measurements.
The unit hertz (Hz) is the standard International System of Units (SI) unit for frequency, defined as one cycle per second. However, practical applications often require larger or smaller scales, leading to the use of kilohertz (kHz), megahertz (MHz), and gigahertz (GHz) in radio, telecommunications, and computing. Additionally, angular frequency expressed in radians per second (rad/s) is common in theoretical physics and mathematics, while revolutions per minute (RPM) is widely used for mechanical rotation. Cycles per second (cps) is essentially equivalent to hertz but was used historically before the term hertz became standard.
This frequency converter runs entirely in your browser without any external dependencies or data collection. When you enter a value and select units, the tool performs calculations instantly using JavaScript. You can convert between any of the supported units and immediately see the result. The interface includes a swap button to quickly reverse your input and output units, and a copy button to easily transfer the result to your clipboard. Because everything happens locally on your device, your conversions remain completely private and secure without any risk of exposure to third parties or external servers.

FAQ
What units does the frequency converter support?
The frequency converter supports Hz, kHz, MHz, GHz, rad/s, RPM, and cps (cycles per second). You can enter any unit and see conversions to all others instantly.
How do you convert between Hz and rad/s?
To convert from Hz to rad/s, multiply by 2π (approximately 6.283185307). To convert from rad/s to Hz, divide by 2π. For example, 60 Hz equals about 376.99 rad/s.
Is the frequency converter free to use?
Yes, the frequency converter is completely free with no limits. You can convert as many values as you need without any charges or subscriptions.
Does the frequency converter store or send my data?
No, all frequency conversions happen entirely in your browser using client-side JavaScript. No data is uploaded, stored, or shared with any server.
