Frequency Converter
Convert frequency between hertz, kilohertz, megahertz, gigahertz, and revolutions per minute (RPM).
Formula: multiply the source value by 60
Quick Conversions
About this tool
Frequency is cycles per second (hertz). RPM is treated as revolutions per minute: 60 RPM = 1 Hz.
How to use it
Enter a frequency, pick units, and read the live conversion.
value_to = value_from × (from_in_hertz / to_in_hertz)
Examples
60 Hz to RPM
60 × 60 = 3,600 RPM.
3,000 RPM to Hz
3,000 × 0.0166667 = 50 Hz.
2.4 GHz to MHz
2.4 × 1,000 = 2,400 MHz.
Every unit expressed in hertz
| Unit | Equal to (Hz) |
|---|---|
| 1 hertz (Hz) | 1 |
| 1 kilohertz (kHz) | 1,000 |
| 1 megahertz (MHz) | 1,000,000 |
| 1 gigahertz (GHz) | 1,000,000,000 |
| 1 revolution per minute (RPM) | 0.0166666667 |
FAQ
Is RPM a frequency?
Yes, if one revolution is one cycle. 1 Hz = 60 RPM.
Are angular frequency (rad/s) included?
No. Use the angle and time converters if you need rad/s.
How does RPM relate to hertz?
One hertz is one cycle per second and RPM counts revolutions per minute, so 1 Hz = 60 RPM.
