The hertz is one cycle per second.
Hertz to Microhertz Converter — Hz to uHz
Convert Hertz (Hz) to Microhertz (uHz) using the exact conversion factor (1 hertz = 1,000,000 microhertz). See the formula, worked examples, conversion table, history, and common uses.

About Converting Hertz to Microhertz
Hertz and Microhertz both describe how fast something cycles or rotates, and the conversion is a routine part of reading a car tachometer or motor spec sheet against a scientific frequency figure. Hertz is most often used for electrical power frequency (50/60 hz worldwide).
Formula
microhertz = hertz × 1000000
This factor comes from each unit's defined relationship to the category's base unit: 1 hertz equals 1 base unit, and 1 microhertz equals 0.000001 base units, so dividing one by the other gives the direct hertz-to-microhertz factor of 1000000.
Simple example
1 Hz × 1000000 = 1,000,000 uHz
1 hertz = 1,000,000 microhertz.
Real-world example
1,000 Hz × 1000000 = 1,000,000,000 uHz
1,000 hertz = 1,000,000,000 microhertz.
Conversion table
| Hertz (Hz) | Microhertz (uHz) |
|---|---|
| 60 Hz | 60,000,000 uHz |
| 600 Hz | 600,000,000 uHz |
| 1,000 Hz | 1,000,000,000 uHz |
| 3,000 Hz | 3,000,000,000 uHz |
| 6,000 Hz | 6,000,000,000 uHz |
| 10,000 Hz | 10,000,000,000 uHz |
Reverse conversion: Microhertz to Hertz
1 uHz × 0.000001 = 0.000001 Hz
1 microhertz = 0.000001 hertz.
hertz = microhertz × 0.000001

Understanding the Hertz
Hertz (Hz) measures frequency. The hertz is the SI derived unit of frequency: one cycle per second. It is classified as a SI derived unit.
Where it's used: Standard scientific unit worldwide; also everyday (AC power frequency, radio, audio)
Uses of the Hertz today
- Electrical power frequency (50/60 Hz worldwide)
- Radio, audio, and signal processing
- Computer processor clock speeds (GHz)
History of the Hertz
The hertz is named after Heinrich Hertz, who in 1886-1889 was the first to conclusively demonstrate the existence of electromagnetic waves predicted by Maxwell's equations. The unit ('cycles per second') was renamed in his honor and adopted internationally in 1930, becoming the SI derived unit of frequency in 1960.
Historical origin. Hertz was not the invention of a single named person; it developed through the process described above.
Understanding the Microhertz (uHz)
Microhertz is 0.000001 hertz units.

Frequently asked questions
How many microhertz are in 1 hertz?
1 hertz equals 1,000,000 microhertz, using the exact defined conversion factor rather than an estimate.
How do I convert hertz to microhertz?
Multiply the hertz value by 1000000. The converter above does this instantly to whatever precision you set.
How do I convert microhertz back to hertz?
Use the reverse factor: 1 microhertz equals 0.000001 hertz. You can also use the swap control in the converter above to flip the direction instantly.
What is a hertz?
Hertz (Hz) measures frequency. The hertz is the SI derived unit of frequency: one cycle per second. It is classified as a SI derived unit.
What is a microhertz?
Microhertz (uHz) is a unit of frequency.
Is the hertz to microhertz conversion exact?
Yes. Both hertz and microhertz are defined by fixed standards rather than physical artifacts, so the factor of 1000000 used above is exact to as many digits as you choose to display.
Where is the hertz still used today?
Standard scientific unit worldwide; also everyday (AC power frequency, radio, audio)
