Enter a frequency value and choose a from/to unit to convert between Hz, kHz, MHz, GHz, and RPM.
Your result
60
Converted value
AI explanation
Formula
Converted value = amount × (from-unit-to-hertz factor) ÷ (to-unit-to-hertz factor)Worked example
1 hertz to RPM
| Field | Value |
|---|---|
| Amount | 1 |
| From unit | hz |
| To unit | rpm |
| Converted value | 60 |
Assumptions
- RPM (revolutions per minute) converts to hertz as RPM ÷ 60, since 1 Hz means 1 full cycle (revolution) per second.
Frequently asked questions
How do I convert engine RPM to hertz?
Divide RPM by 60 — for example, an engine idling at 900 RPM completes 15 revolutions per second, i.e. 15 Hz.
What frequencies do processors and radio use?
Computer processor clock speeds are typically given in GHz (billions of cycles per second), while radio broadcast frequencies are usually in kHz (AM) or MHz (FM).
Is frequency the same as pitch in sound?
Frequency (Hz) directly determines a sound's pitch — higher frequency means higher pitch. Human hearing typically ranges from about 20 Hz to 20,000 Hz (20 kHz).
