Facts and limits of this method
| Base unit | Hertz — all other units convert through it |
|---|---|
| Metric prefixes | kHz = 10³ Hz, MHz = 10⁶ Hz, GHz = 10⁹ Hz, THz = 10¹² Hz |
| 1 revolution per minute | 1/60 Hz (≈0.016667 Hz) |
| Total units | 6 — Hz, kHz, MHz, GHz, THz, RPM |
When it misleads you
- The calculation happens in two steps: the value is first converted to hertz, then from hertz to the target unit, so choosing the same unit for "from" and "to" leaves the result unchanged.
- Revolutions per minute (RPM) is a rotational speed unit, not an oscillatory frequency in the strict physics sense; converting to hertz (1 RPM = 1/60 Hz) is correct when "frequency" means the number of full revolutions per second.
- The converter doesn't convert frequency to wavelength (that requires the wave's propagation speed, such as the speed of light for radio waves) — it's purely a unit-to-unit frequency conversion.
- Rounding is applied only to the displayed result — internal calculations use the full precision of JavaScript floating-point numbers.
How it is calculated
Each of the six units has a preset conversion factor to hertz — for example, 1 MHz = 1,000,000 Hz, 1 RPM = 1/60 Hz.
The entered value is multiplied by the factor of the selected "from" unit, giving frequency in hertz.
The frequency in hertz is divided by the factor of the "to" unit, giving the result in the target unit.
The result is rounded to the chosen number of decimal places and updates instantly whenever the value, units or precision change.
Questions and answers
How does RPM relate to hertz?
1 revolution per minute equals 1/60 hertz (about 0.016667 Hz), because a hertz is one event (a revolution, in this case) per second, not per minute.
Can I convert a processor's gigahertz to megahertz?
Yes, the converter works for any pair among the six units, including the GHz and MHz units commonly used for CPU clock speed.
Does the converter convert frequency to wavelength?
No, this is a conversion between frequency units; converting to wavelength requires an additional formula involving the propagation speed of the specific wave type.
