Writing out MHz Band and the kHz Band?

Click For Summary

Discussion Overview

The discussion centers around the correct representation of frequencies in the MHz and kHz bands, specifically how to express these frequencies in Hertz. Participants explore various examples of radio frequencies and the appropriate notation for expressing them numerically.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant claims that 909.5 MHz can be expressed as 909,500,000 Hz and describes it verbally as "9 Hundred and 9 Thousand 5 Million Hertz."
  • Another participant questions the accuracy of 909.5 MHz, suggesting it might actually be 90.9 MHz, and notes that AM frequencies typically fall within the kHz range.
  • A participant asks how to express the frequency of an FM station, specifically 101.5 FM, and proposes writing it as 1,015,000 Hz.
  • There is a correction regarding the verbal expression of 909.5 MHz, stating it should be "9 hundred and 9 million, 5 hundred thousand," and a suggestion to use MHz notation to avoid confusion.
  • One participant discusses a shortwave radio frequency of 6050 kHz and questions the omission of a decimal point, suggesting it should be written as 6050,000 kHz.
  • Another participant corrects this, stating it should be expressed as 6,050,000 Hertz instead of kHz.
  • A suggestion is made for participants to study SI units and metric prefixes to avoid confusion in frequency representation.

Areas of Agreement / Disagreement

Participants express differing views on the correct representation of frequencies, with some corrections and clarifications made, but no consensus is reached on the best practices for expressing these frequencies.

Contextual Notes

There are unresolved issues regarding the accuracy of frequency values and the preferred notation for expressing them, as well as potential confusion stemming from the use of different units (MHz vs. kHz).

I need some help with FREQ. on the MHz Band and the kHz Band?

If I am on a Radio that displays the FREQ
909.5 MHz
I know I would write this out as
909,500,000 Hz
and this is
9 Hundred and 9 Thousand 5 Million Herts

Am I right?
 
Engineering news on Phys.org
as far as i know typical fm is in MHZ ( 87 - 105 or something don't know exactly). So, 909.5Mhz on radio seems wrong. are you sure its not 90.9 Mhz. AM works in hundreds kilo hertz range

in any case: 909.5Mhz => 909.5 x 10^6
Mega: 10^6 kilo: 10^3

hope this helps,

OK let me ask this way.

An FM station of
NJ 101.5 FM I have it on every Day.

So would I write it out as 1,015,000 Hz

No that is not how to write it, it should be 9 hundred and 9 million, 5 hundred thousand.

In any achemic situation it would always be better to use the MHz notation. Just to avoid the errors in your verbal effort.

yes 101,500,000Hz is a correct expression of 101.5MHz but why bother?
 
OK I undersstand now.

Now I am on a Shortwave Radio and the display says
6050 kHz
now my Radio shows no Point because this is showing me in kHz I get this.

But would I be right that they are not showing me the Point just to make it easy for the user but if we write it out we will write
6050,000 kHz,

No. It would be 6,050,000 Hertz. NOT KHz.
 
biferi, May I suggest that you study "SI units" (International System of Units), also known as “metric prefixes”? The metric measurements are all in decimal form, and are used very consistently from one parameter to another. (Parameters are things that you measure, such as: length, mass, charge, density, heat, temperature, frequency, etc.) I recommend you memorize them and avoid confusion forever afterwards.
