About frequency conversions
Enter a value and choose the units to convert between. Each frequency unit is defined against a single base unit, so any pair lines up consistently, the table shows your value in every frequency unit at once.
What this does
A frequency converter changes a rate of repetition between hertz, kilohertz, megahertz, gigahertz, and revolutions per minute.
How to use it
- Enter a value and pick its unit.
- Choose the unit to convert to.
- Read the converted result instantly.
- Swap the units to reverse the conversion.
How it works
Each value is converted to hertz first and then to the target unit. One hertz is one cycle per second; RPM counts cycles per minute, so 60 RPM equals 1 Hz. Each metric step up is a factor of 1,000.
Hz = RPM ÷ 60
Example
One megahertz is 1,000,000 hertz, and 3,000 RPM is 50 Hz.
