Frequency Converter

Convert between Hz, kHz, MHz, GHz, and more.

Frequently Asked Questions

What frequency units are supported?

The converter handles: hertz (Hz), kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz), revolutions per minute (RPM), revolutions per second (RPS), and radians per second. It also converts between frequency and period (the time for one complete cycle).

How do I convert frequency to period?

Period = 1 / Frequency. A 60 Hz signal has a period of 1/60 second = 16.67 milliseconds. A 1 MHz signal has a period of 1 microsecond. The converter shows the period in the most appropriate unit (seconds, milliseconds, microseconds, or nanoseconds) based on the frequency.

What is the relationship between Hz, kHz, MHz, and GHz?

1 kHz = 1,000 Hz. 1 MHz = 1,000 kHz = 1,000,000 Hz. 1 GHz = 1,000 MHz = 1,000,000,000 Hz. Audio frequencies are typically in Hz-kHz range. Radio frequencies are in MHz-GHz. Computer processors operate in GHz. The converter handles the full range from millihertz to terahertz.

How do I convert RPM to Hz?

Divide RPM by 60 to get Hz (cycles per second). A motor spinning at 3,600 RPM = 60 Hz. A car engine at 3,000 RPM = 50 Hz. Conversely, multiply Hz by 60 to get RPM. This conversion is common in motor specifications, turntable speeds, and rotating machinery.

What frequencies are used in everyday technology?

Power grid: 50 Hz (Europe) or 60 Hz (US). Audible sound: 20 Hz - 20 kHz. AM radio: 540-1600 kHz. FM radio: 88-108 MHz. WiFi: 2.4 GHz and 5 GHz. 5G cellular: 600 MHz - 39 GHz. GPS: 1.575 GHz. Microwave oven: 2.45 GHz. Computer processor: 3-5 GHz.
