How many hertz in a frequency?

Answer 1

It can be as many as you wish...

Actually, Frequency & Hertz is totally two different category or level.

Frequency is a measurement parameter/ variable.

Hertz is the unit of measurement for a parameter/ variable.

This can be analogue as

Frequency - Velocity

Hertz - miles/ second

Answer 2

One is not necessarily better than the other, as a generality. Hertz (Hz) is a unit used to measure frequency of oscillations. The oscillations could be ocean waves, a pendulum swinging, sound waves, electromagnetic waves (light, radio signals, microwaves, x-rays, etc.).

So 1 Hertz is 1 cycle (oscillation) per second. 1 KHz is 1000 cycles per second. So one may be better to use depending on the scale of what you're describing. For example, the AC voltage in your home is 60 Hz (at least in the United States), or some countries use 50 Hz. In sound, 60 Hz is approximately the frequency of the low B-flat note just below the Bass-Cleff staff. 440 Hz is the frequency of the A Note just above 'middle C'. 20000 Hz (20 KHz) is near the upper range of adult human hearing. AM Radio frequency range is 500 KHz - 1600 kHz, and FM Radio is in the 88 MHz to 107 MHz range (88000 KHz - 107000 kHz). Microwaves are in the GigaHertz range (1000000 KHz or 1000000000 Hz). So neither Hz nor kHz would not be very convenient for these.

As you go up the scale (visible light is in the 1014 to 1015 Hz range), Scientific Notation may be used, then it makes more sense to use Hz, rather than kHz .

Answer 3

There is 1,000,000 Hz in 1 MHz. MHz stands for megahertz, and the prefix mega numerically means 106.

Answer 4

Hertz is the unit of frequency and represents the number of cycles per second. Therefore, the value in hertz indicates how many cycles occur in one second.

Answer 5

Every one khz = 1000 hz

Answer 6

20kHz means 20 000 cycles per second.
