How to Use the Frequency Converter

Basic Conversion

Enter Your Value

Type a number in the input field. Numbers are automatically formatted with thousand separators for easy readability (e.g., 1,000,000).

Select Source Unit

Choose your starting unit from the dropdown menu. You can type to search for a specific unit quickly.

View Instant Results

All conversions appear immediately below in all enabled units. No button clicks required!

Customizing Your Experience

Adjust Decimal Precision

Use the "Decimals" dropdown to control how many decimal places are shown. Choose from 2, 4, 6, 8 decimals, or select "Auto" to let the tool decide based on the value.

Show/Hide Units

Click "Customize Units" to toggle which units appear in your results. Perfect for users who regularly work with specific unit groups like metric or rotational.

Copying Results

Click on any result row to copy that specific value instantly. For multiple values, use the "Copy All Results" button to copy everything at once in a clean, ready-to-paste format.

Quick Reference

Not sure about a unit? Click "Unit Reference" to see a comprehensive table explaining each unit, its value relative to the base unit (Hertz), and common use cases.

Tips for Common Conversions:

CPU speed: 1 GHz = 1,000 MHz = 1,000,000,000 Hz
Motor speed: 60 RPM = 1 Hz (one revolution per second)
Music tempo: 120 BPM = 2 Hz (two beats per second)
Video: 60 FPS = 60 Hz refresh rate

Features

Instant Conversion

Results update in real-time as you type. No need to click a button or wait for processing—just enter your value and see all conversions immediately.

Comprehensive Unit Support

Convert between 16 different frequency units spanning electronic, mechanical, audio, and video measurement systems.

Metric units (Hz to THz)
Rotational units (RPM, rad/s)
Practical units (BPM, FPS)

Smart Input Formatting

Large numbers are automatically formatted with thousand separators (e.g., 1,000,000 instead of 1000000), making it easier to read and verify your input.

Searchable Unit Selection

The unit dropdown includes a search function. Start typing the unit name or symbol (like "mhz" or "rpm") to quickly find what you need.

Customizable Display

Choose which units appear in your results. Group units by category and toggle each one individually.

Filter by metric, rotational, or practical
Focus on relevant units for your field

Precision Control

Select from multiple decimal precision options (2, 4, 6, 8) or use Auto mode. Higher precision is useful for scientific calculations, while lower precision keeps results easy to read.

One-Click Copy

Copy individual results or all results at once. Values are copied in a clean format, ready to paste into documents, spreadsheets, or technical reports.

Unit Reference Guide

Built-in reference panel explains each unit's value and typical usage. Helpful when you encounter unfamiliar units like rad/s, THz, or cph.

Works Everywhere

Fully responsive design works on desktop, tablet, and mobile devices. Calculate frequency conversions wherever you are—at the studio, in the lab, or on site.

Frequently Asked Questions

What is the difference between Hz and RPM?

Hertz (Hz) measures cycles per second and is the SI unit of frequency. RPM (Revolutions per Minute) measures rotations per minute.

Conversion: 1 Hz = 60 RPM

Example: A motor spinning at 3,600 RPM rotates at 60 Hz.

How do I convert MHz to GHz?

Divide MHz by 1,000 to get GHz.

Example: 2,400 MHz = 2.4 GHz (common WiFi frequency)

Use this converter for instant, accurate results without manual calculation.

What is BPM used for?

BPM (Beats per Minute) measures tempo in music and heart rate in medicine.

Music: Dance music typically ranges from 120-150 BPM
Health: Resting heart rate is 60-100 BPM
Conversion: 120 BPM = 2 Hz (two beats per second)

What frequency is 5G wireless?

5G networks operate across multiple frequency bands:

Low-band: 600-900 MHz (wide coverage, moderate speed)
Mid-band: 2.5-4 GHz (balanced coverage and speed)
High-band (mmWave): 24-47 GHz (fastest speeds, limited range)

Higher frequencies offer faster speeds but shorter range.

How do I convert rad/s to RPM?

Multiply rad/s by 60/(2π) ≈ 9.549 to get RPM.

Example: 10 rad/s ≈ 95.49 RPM

This converter handles the calculation automatically with high precision, eliminating the need for manual formulas.

What frame rate should I use for video?

Common frame rates and their applications:

Frame Rate	Use Case	Characteristics
24 FPS	Cinema, Film	Cinematic look, traditional film standard
30 FPS	TV, Web Video	Standard for broadcast and online content
60 FPS	Sports, Gaming	Smooth motion, ideal for fast action
120 FPS	Slow Motion	High-quality slow-mo playback

Higher FPS means smoother motion but larger file sizes.

What is the frequency of middle C on a piano?

Middle C (C4) has a frequency of approximately 261.63 Hz

Musical frequency reference:

Concert pitch A4 is standardized at 440 Hz
Musical frequencies double with each octave (A5 = 880 Hz)
Each semitone increases frequency by a factor of 2^1/12 ≈ 1.059

How accurate are the conversions?

Conversions use internationally recognized conversion factors with high precision. For most practical purposes, the results are accurate to many decimal places.

Professional Accuracy: Use the precision selector to display the accuracy level you need—from 2 decimals for quick estimates to 8 decimals for scientific calculations.
