frequency Converter

Convert frequency units instantly with our free online frequency converter. Whether you need to convert Hz to kHz, MHz to GHz, or any other frequency conversion, our calculator provides accurate results for all your electronics, radio, and audio engineering needs.

Frequency conversion is essential in electronics, telecommunications, audio engineering, and radio communications. Our tool supports all common frequency units from Hertz (Hz) to Terahertz (THz), plus rotational frequencies like RPM and radians per second.

Common Frequency Units:

• Hertz (Hz): The base unit of frequency, representing one cycle per second. Used for low frequencies like sound waves (20 Hz - 20 kHz).
• Kilohertz (kHz): 1,000 Hz. Common in audio frequencies, AM radio (540-1600 kHz), and low-frequency electronics.
• Megahertz (MHz): 1,000,000 Hz. Used for FM radio (88-108 MHz), TV broadcasts, and computer processors.
• Gigahertz (GHz): 1,000,000,000 Hz. Modern CPU frequencies (2-5 GHz), WiFi (2.4 GHz, 5 GHz), and microwave frequencies.
• Terahertz (THz): 1,000,000,000,000 Hz. Used in advanced research, infrared radiation, and molecular spectroscopy.
• Revolutions per Minute (RPM): Rotational frequency used for motors, engines, and mechanical systems.

Basic Frequency Conversions:

• Hz to kHz: Divide by 1,000 (f_kHz = f_Hz ÷ 1,000)
• kHz to Hz: Multiply by 1,000 (f_Hz = f_kHz × 1,000)
• MHz to Hz: Multiply by 1,000,000 (f_Hz = f_MHz × 1,000,000)
• GHz to MHz: Multiply by 1,000 (f_MHz = f_GHz × 1,000)
• RPM to Hz: Divide by 60 (f_Hz = RPM ÷ 60)
• Hz to RPM: Multiply by 60 (RPM = f_Hz × 60)

Step-by-Step Conversion Examples:

Convert 50 Hz to kHz:

50 Hz ÷ 1,000 = 0.05 kHz

Convert 2.4 GHz to MHz:

2.4 GHz × 1,000 = 2,400 MHz

Convert 1800 RPM to Hz:

1800 RPM ÷ 60 = 30 Hz

Common Uses for Frequency Conversion:

• Audio Engineering: Converting between Hz and kHz for equalizers, crossovers, and speaker specifications (20 Hz - 20 kHz range).
• Radio Communications: Converting AM radio frequencies (kHz) to FM frequencies (MHz) for broadcasting and receiver tuning.
• Computer Hardware: Understanding CPU speeds (GHz), RAM frequencies (MHz), and system bus speeds.
• Electronic Circuit Design: Calculating oscillator frequencies, clock signals, and filter cutoff frequencies.
• Motor Control: Converting RPM to Hz for variable frequency drives (VFDs) and motor speed control.
• Medical Equipment: Ultrasound frequencies (MHz), MRI frequencies, and therapeutic equipment calibration.
• Scientific Research: Spectroscopy, atomic transitions, and electromagnetic radiation analysis.
