Frequency converter
Cycles per second — clocks, radio, audio. 7 units, converted from one table of exact factors.
—
1 hertz in every other frequency unit
Computed by the same engine that runs the converter above, so these can never drift apart from it.
| From | Equals | Unit |
|---|---|---|
| 1 hertz | 0.001 | kilohertz (kHz) |
| 1 hertz | 0.000001 | megahertz (MHz) |
| 1 hertz | 1.000000000 × 10^-9 | gigahertz (GHz) |
| 1 hertz | 60 | revolution/minute (rpm) |
| 1 hertz | 6.283185307 | radian/second (rad/s) |
| 1 hertz | 360 | degree/second (°/s) |
What each unit actually is
Most converters give you a number and stop. Where a figure is exact by definition we say so, and where it is an average or shifts with conditions we say that too — that is usually the thing you needed to know.
| Unit | Symbol | What it actually is |
|---|---|---|
| hertz | Hz | One cycle per second. |
| kilohertz | kHz | |
| megahertz | MHz | |
| gigahertz | GHz | |
| revolution/minute | rpm | One sixtieth of a hertz. |
| radian/second | rad/s | Divide by 2π to get hertz. |
| degree/second | °/s |
