Hertz (Hz)
Definition: The hertz (symbol: Hz) is the derived unit of frequency in the International System of Units (SI). It is defined as one cycle or event per second.
History/origin: The unit is named after the German physicist Heinrich Hertz, who made important scientific contributions to the study of electromagnetism in the late 19th century.
Current use: Hertz is the fundamental unit used to measure the frequency of sound waves, electrical currents (like the 50/60 Hz AC power in your home), and all electromagnetic radiation.
Megahertz (MHz)
Definition: A megahertz (symbol: MHz) is a unit of frequency equal to one million (1,000,000) cycles per second.
History/origin: Historically known as "megacycles per second," the MHz became widely used during the popularization of FM radio and VHF/UHF television broadcasting in the mid-20th century.
Current use: MHz is the standard measurement for FM radio broadcasts, analog television signals, two-way radios (walkie-talkies), and the clock speeds of early computer processors (like the classic 66 MHz Pentium).
Hertz (Hz) to Megahertz (MHz) Conversion Table
| Hertz (Hz) [hz] | Megahertz (MHz) [mhz] |
|---|---|
| 0.01 hz | 0.00000001 mhz |
| 0.1 hz | 0.0000001 mhz |
| 1 hz | 0.000001 mhz |
| 2 hz | 0.000002 mhz |
| 3 hz | 0.000003 mhz |
| 5 hz | 0.000005 mhz |
| 10 hz | 0.00001 mhz |
| 20 hz | 0.00002 mhz |
| 50 hz | 0.00005 mhz |

How to Convert Hertz (Hz) to Megahertz (MHz)
1 hz = 0.000001 mhz
1 mhz = 1000000 hz
Example: convert 15 hz to mhz:
15 hz = 15 × 0.000001 mhz = 0.000015 mhz
Did You Know?
- Did you know? A healthy young human ear can hear sound frequencies ranging from 20 Hertz (very low bass) up to 20,000 Hertz (very high pitch).
- FM radio stations broadcast in Megahertz (MHz). If your favorite station is 89.6 FM, their radio tower is transmitting electromagnetic waves at 89.6 million cycles per second!
