Frequency Converter
Quick answer: Choose a starting unit and a target unit, then enter a value. Common conversions: 1 MHz = 1,000 kHz; 1 Hz = 0.001 kHz; 1 Hz = 0.000001 MHz. This converter covers 8 frequency units.

Use the Frequency Converter
Frequency formula and what each symbol means
target = value × (factor of starting unit ÷ factor of target unit), where each factor is the unit value in Hz.
| Symbol | Meaning |
|---|---|
| value | The number you want to convert |
| factor | The unit’s size expressed in the base unit (Hz) |
Frequency examples
MHz to kHz
10 MHz = 10,000 kHz.
Hz to kHz
10 Hz = 0.01 kHz.
Hz to MHz
10 Hz = 0.00001 MHz.
How to calculate Frequency step by step
- Choose the starting unit and the target unit.
- Enter your value.
- Read the converted value, plus the conversion factor in both directions.

How to read your Frequency result
One hertz is one cycle per second. Rotational speed in rpm converts to hertz by dividing by 60, so 3,000 rpm is 50 Hz.
| UNIT | SYMBOL | EQUALS | VALUE OF 1 HZ |
|---|---|---|---|
| Hertz | Hz | 1 Hz = 1 Hz | 1 Hz |
| Kilohertz | kHz | 1 kHz = 1,000 Hz | 0.001 kHz |
| Megahertz | MHz | 1 MHz = 1,000,000 Hz | 0.000001 MHz |
| Gigahertz | GHz | 1 GHz = 1,000,000,000 Hz | 1×10⁻⁹ GHz |
| Terahertz | THz | 1 THz = 1,000,000,000,000 Hz | 1×10⁻¹² THz |
| Millihertz | mHz | 1 mHz = 0.001 Hz | 1,000 mHz |
| Revolution per minute | rpm | 1 rpm = 0.016666667 Hz | 60 rpm |
| Radian per second | rad/s | 1 rad/s = 0.15915494 Hz | 6.283185 rad/s |
Common mistakes when calculating Frequency
- Confusing hertz (cycles per second) with radians per second: ω = 2πf.
- Forgetting to divide rpm by 60.
- Mixing mHz (milli) with MHz (mega).
Frequency FAQ
How many Hz is 60 rpm?
1 Hz.
How many kHz in a MHz?
1,000.
What is the radian frequency of 50 Hz?
About 314.16 rad/s.
What is the base unit for frequency?
This converter uses hertz (Hz) as the common base unit: every value is first converted to it and then to the target unit.
How do I convert between two frequency units?
Choose the starting and target units, enter the value and read the result. By hand: convert to the base unit with the table, then divide by the target unit factor.
How many kHz are in 1 megahertz?
1 MHz = 1,000 kHz.
How many kHz are in 1 hertz?
1 Hz = 0.001 kHz.
How many MHz are in 1 hertz?
1 Hz = 0.000001 MHz.
Which frequency units does this converter support?
It covers 8 units: hertz (Hz), kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz), millihertz (mHz), revolution per minute (rpm), radian per second (rad/s).
How accurate is the frequency converter?
Results are calculated at full double precision and shown to about 8 significant figures. Round the answer to the precision of your original measurement; a result cannot be more accurate than the number you started with.
