About Converting Revolutions per minute to Microhertz
Revolutions per minute and Microhertz are both scientific-measurement units, spanning everything from atomic and laboratory scales to astronomical distances — the kind of conversion that comes up constantly in physics, chemistry, and astronomy when a result needs to move between conventions used in different subfields. Revolutions per minute is most often used for engine and motor speed specifications (car tachometers).
Formula
microhertz = revolutions per minute × 16666.6666667
This factor comes from each unit's defined relationship to the category's base unit: 1 revolutions per minute equals 0.0166666666667 base units, and 1 microhertz equals 0.000001 base units, so dividing one by the other gives the direct revolutions per minute-to-microhertz factor of 16666.6666667.
Simple example
1 rpm × 16666.66667 = 16,666.66667 uHz
1 revolutions per minute = 16,666.66667 microhertz.
Real-world example
10 rpm × 16666.66667 = 166,666.6667 uHz
10 revolutions per minute = 166,666.6667 microhertz.
Conversion table
| Revolutions per minute (rpm) | Microhertz (uHz) |
|---|---|
| 0.001 rpm | 16.66666667 uHz |
| 0.01 rpm | 166.6666667 uHz |
| 1 rpm | 16,666.66667 uHz |
| 10 rpm | 166,666.6667 uHz |
| 100 rpm | 1,666,666.667 uHz |
| 1,000 rpm | 16,666,666.67 uHz |
Reverse conversion: Microhertz to Revolutions per minute
1 uHz × 0.00006 = 0.00006 rpm
1 microhertz = 0.00006 revolutions per minute.
revolutions per minute = microhertz × 0.00006

Understanding the Revolutions per minute
Revolutions per minute (rpm) measures rotational speed. RPM (revolutions per minute) equals hertz divided by 60, since one revolution per minute is 1/60 of a cycle per second. It is classified as a Non-SI unit (mechanical/automotive).
Where it's used: Used worldwide in automotive, mechanical, and industrial contexts
Uses of the Revolutions per minute today
- Engine and motor speed specifications (car tachometers)
- Industrial machinery and turbine speed ratings
- Hard drive and disc rotational speed
History of the Revolutions per minute
RPM developed alongside rotating machinery in the 19th-century industrial era as a practical, directly-readable way to describe rotational speed (a tachometer counting revolutions per minute), rather than converting to the more abstract cycles-per-second used in physics.
Historical origin. Revolutions per minute 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 revolutions per minute?
1 revolutions per minute equals 16,666.66667 microhertz, using the exact defined conversion factor rather than an estimate.
How do I convert revolutions per minute to microhertz?
Multiply the revolutions per minute value by 16666.66667. The converter above does this instantly to whatever precision you set.
How do I convert microhertz back to revolutions per minute?
Use the reverse factor: 1 microhertz equals 0.00006 revolutions per minute. You can also use the swap control in the converter above to flip the direction instantly.
What is a revolutions per minute?
Revolutions per minute (rpm) measures rotational speed. RPM (revolutions per minute) equals hertz divided by 60, since one revolution per minute is 1/60 of a cycle per second. It is classified as a Non-SI unit (mechanical/automotive).
What is a microhertz?
Microhertz (uHz) is a unit of scientific units.
Is the revolutions per minute to microhertz conversion exact?
Yes. Both revolutions per minute and microhertz are defined by fixed standards rather than physical artifacts, so the factor of 16666.66667 used above is exact to as many digits as you choose to display.
Where is the revolutions per minute still used today?
Used worldwide in automotive, mechanical, and industrial contexts
Why does this category span everything from atomic to astronomical scales?
Scientific work spans an enormous range of physical scales, from atomic distances (measured in angstroms or atomic mass units) to interstellar distances (measured in astronomical units or parsecs), so this category groups SI-derived and scale-specific units that researchers commonly need to convert between within their field.
