Convert frequency units including hertz, kilohertz, megahertz, gigahertz, terahertz, cycles per second, revolutions per minute, radians per second, and more.
Hertz to kilohertz:
1 Hz = 0.001 kHz
Kilohertz to hertz:
1 kHz = 1,000 Hz
Megahertz to hertz:
1 MHz = 1,000,000 Hz
Revolutions per minute to hertz:
1 rpm = 0.0166667 Hz
Frequency conversions are useful for electrical systems, AC power, motors, vibration analysis, audio signals, radio frequencies, wireless communication, rotating machinery, and wave calculations.
Use this converter when comparing SI frequency prefixes, rotational speed, angular frequency, and cycle-based units.
Your result shows the entered frequency converted from the starting unit into the selected ending unit. The calculator also shows the conversion rate used so you can verify the calculation.
For electrical, mechanical, audio, vibration, or communication work, make sure the frequency unit matches your equipment rating, signal reference, motor speed, waveform data, or calculation sheet.
Frequency is the number of cycles, waves, rotations, or repeating events that occur per second.
The SI unit of frequency is the hertz, abbreviated as Hz.
Yes. One hertz equals one cycle per second.
One revolution per minute equals 0.0166667 hertz.
This converter is designed for frequency magnitude conversions, so it uses non-negative values.
