Hertz to Revolution Per Minute Converter
How to Convert Hertz to Revolution Per Minute
1 hertz = 60 revolutions per minute exact
Revolution Per Minute = Hertz × 60
Example: 1 Hz × 60 = 60 rpm
Reverse Conversion
To convert revolutions per minute back to hertz:
- Remember, 1 revolution per minute equals 0.0166667 hertz.
- To convert 60 rpm to Hz, multiply
60 x 0.0166667, resulting in1 Hz.
exact This conversion factor is exact by international definition.

Definition of Hertz
Hertz: The SI Unit of Frequency
The hertz (symbol: Hz) is the SI unit of frequency, defined as one cycle per second. It is named after Heinrich Rudolf Hertz, who first conclusively proved the existence of electromagnetic waves in 1887. One hertz means that an event repeats once per second.
Conversions to Other Units of Measurement:
- Kilohertz (kHz): 1 Hz equals 0.001 kHz. Kilohertz is commonly used for audio frequencies and AM radio broadcasting.
- Megahertz (MHz): 1 Hz equals 0.000001 MHz. Megahertz is used for FM radio and television broadcasting frequencies.
- Gigahertz (GHz): 1 Hz equals 10⁻⁹ GHz. Gigahertz is used for microwave frequencies, Wi-Fi, and modern processor clock speeds.
- Revolutions per Minute (rpm): 1 Hz equals 60 rpm. This conversion is fundamental in mechanical and electrical engineering for relating rotational speed to frequency.
- Radians per Second (rad/s): 1 Hz equals 2π rad/s (approximately 6.2832 rad/s). This angular frequency is essential in physics and signal processing.
The hertz is fundamental across science and engineering, from describing sound pitch and radio waves to processor clock speeds and power grid frequencies.

Definition of Revolution Per Minute
Revolution per Minute: Rotational Speed Unit
The revolution per minute (symbol: rpm or r/min) is a unit of rotational frequency expressing the number of complete turns in one minute. It is one of the most widely used units in mechanical engineering, automotive, and industrial applications. From car engines to hard drives, rpm is the standard way to express how fast something spins.
Conversions to Other Units of Measurement:
- Hertz (Hz): 1 rpm equals exactly 1/60 Hz (approximately 0.01667 Hz). A car engine at 3,000 rpm operates at 50 Hz.
- Radian per Second (rad/s): 1 rpm equals π/30 rad/s (approximately 0.10472 rad/s). This conversion is essential in dynamics and control engineering.
- Revolution per Second (rps): 1 rpm equals 1/60 rps. At 7,200 rpm (a common hard drive speed), the disk spins 120 times per second.
Common rpm values: ceiling fans (50-300 rpm), car engines at idle (600-1000 rpm), hard drives (5,400-15,000 rpm), jet engines (10,000-25,000 rpm), dental drills (up to 400,000 rpm).

About the Hertz
The hertz is named after Heinrich Hertz (1857-1894), who was the first to conclusively demonstrate the existence of electromagnetic waves predicted by James Clerk Maxwell's equations. Hertz's experiments in 1887 used a spark gap transmitter operating at about 50 MHz.
Power grids worldwide operate at either 50 Hz (Europe, Asia, Africa, most of South America) or 60 Hz (North America, parts of South America and Asia). This frequency determines the "hum" you sometimes hear from electrical equipment.
About the Revolution Per Minute
Vinyl records play at standardized speeds: 33⅓ rpm for LP albums, 45 rpm for singles, and 78 rpm for early shellac records. These speeds were chosen to balance audio quality with playing time and were standardized by the 1950s.
A Formula 1 engine can rev to over 15,000 rpm (limited by regulations), while a diesel truck engine typically operates between 1,200-1,800 rpm. Hard drives commonly spin at 5,400 or 7,200 rpm, with enterprise drives reaching 15,000 rpm.
Frequently Asked Questions
How many revolutions per minute are in one hertz?
One hertz equals 60 revolutions per minute. To convert, multiply the hertz value by 60. For the reverse, divide the revolution per minute value by 60 (or multiply by 0.0166667).
What is 10 hertz in revolutions per minute?
10 hertz = 600 revolutions per minute. This is one of the most commonly searched conversions for this pair.
Is the hertz-to-revolution per minute conversion exact?
Yes. The factor 60 is exact by international definition, not an approximation. Any imprecision comes only from the original measurement, not the conversion.
