Handy Mc to Hertz Conversion Chart

K0FF (K0FF) on December 26, 2002
View comments about this article!

Subject: Handy chart for newcomers to Spectrum studies.

Realizing that the new crop of engineering students, HAM radio operators, and scientists were not around during the turbulent 60's , when Bill Gates was in diapers, a time before cell phones and PCs, back in the days of TTL and DTL and even RTL logic, when changing fonts required a new typing ball for you IBM Selectric, modems were acoustically coupled and a good one ran at 300 Baud, when transistors were germanium, not silicon, when vacuum tubes still held forth, and above all when the MEGACYCLE ruled, I have prepared a couple of charts to make the needed conversions to the new MAGAHERTZ easier.

The Linear chart is easy to use and understand, whereas the Logarithmic chart is provided for more advanced users.

If you need individual assistance in using these charts, please contact the author direct.

Provided for your convenience, the conversion formulas for you file:

MC/s *X/ (X /X) = MHz where X=1

or

Square root of (MC/s * MC/s) = MHz

Another set of charts for the AUDIO ENTHUSIASTS > CYCLES to HERTZ are in the works and will be published as soon as all the tedious math work in finished.

Have Fun

Geo, KFF

Rick-KB1FLR,
Because of the season in which the second chart was posted, we used the old-fashioned Yultide Log method of graphing...but that's another story.

Hey, this is great! Very creative. Will pass this along as required reading to our design team. To further enhance the ham's knowledge of electronics, would you please publish curves on the operation of VHF audio microphones and UHF DC power supplies?

Also, how about a DC to Direct Current conversion chart?

Good stuff--keep it up! Happy New Year,

Don, W8AD

I worked with KFF many years ago. Geo repaired commercial two-way radio equipment that I sold. It is now apparent why my customers always bought new radios from me immediately after having their radios "repaired" by George.

Season's Greetings!

The easiest conversion, as can be seen from your detailed first graph, is to multiply Mcs by its first derivative, to arrive at MHz.

(Mcs x M)=MHz

Since human hearing is best modeled on logs, your second graph will be the most useful, but econ. and finance people will probably need a scale based upon E to the X

Have FUN

KB1FLR - have you heard the old saying, "the shortest distance between two points is a straight line"? If you take a globe and stretch a string between, say, Washington and L.A. it will follow an arc. The "straight line" statement is only true in two-dimentional space, such as on a map. Similarly, if you draw a picture of a log on paper (two dimentional space) it looks like a picture of a log. However, if you apply the Logarian transformation equations to the coordinates of all the lines in the drawing, you get a picture of the log in Log space, which is what was plotted in the second plot. If you apply the Logarian transformations again, you could plot the log on a Log-Log plot. This would show you what a log looks like to another log.

Reminds me of one of the "Strays" blurbs in QST many years ago. The only two I recall were that a Kilocycle is a dangerous two-wheel vehicle, and a pentode was a frog in prison. There were more, but too many milks under the dam have been bypassed to ground since then.

Can you tell me where I can find a good program on-line to do Mc to Hertz conversions?

I think that I remember seeing this chart in the latest Extra class exam question pool. Haven't got this memorized yet, besides who needs it. I'd wish they would take this off the test. These advanced electronics questions are too much to contemplate. Who needs it anyway, no one homebrews anymore?

This is impossible!!! A point is defined as a locus on a line and a line is that which conects two points. If you do not have two points, you cannot have a line but you can't have a point until you have a line to connect them.

To whom it may concern,

I have verified both the linear & log results using a Keuffel & Esser Log Log Duplex slide rule (4081-3).

Both charts agree and each is certified to be accurate to within (minimum) .001 Mhz.

Very nice Geo, but this is really geared to the VHF/UHF experts since it goes from 0-5,000 Mc. Most of us spend more time in the HF bands below 30 Mc. The resolution is not really good enough, say for setting up a schedule on 20 meters. Could you come up with an HF version? Thanks! :-)

Funny stuff, but it reminds us that calling cycles hertz in the first place is dumb. A cycle is a cycle - period. It's time to dump the term hertz.
 
RE: Handy Mc to Hertz Conversion Chart  
by WA9SVD on December 28, 2002 Mail this to a friend!
To K4TBN:

Just to get technical, a cycle is a cycle is IS a cycle. But "cycles" and "Hertz" are not interchangeable. "Cycle" in terms of frequency is meaningless unless it is appended with "per second," or any other time period. Hertz by definition IS "Cycles per second." Don't beat a dead horse; this issue died years ago. Or should I try calling you on my "80 inch" handheld?

To W9XT:
Hi Gary,

You can easily interpolate the values of the chart for use at HF. Just divide the MC/s value by 1000, and multiply the Megahertz value by 0.001. You will have your results in kC/s and kHz. You might even want to plot your own chart using the new figures.
Happy New Year to ALL!!!

With all due respect to the honor and memory of Mr. Henrich Hertz, I still object to having the unit of frequency, namely the cycle / second, named after him.

I still believe the electronics world would have been much better off if the unit of frequency had not been named after Mr. Hertz. It would have been a more appropriate honor to name it after the father of Alternating Current and one of the original geniuses behind what evolved into the General Electric Corporation, namely one Dr. Charles Proteus Steinmetz.

Agreed, "Steinmetzes" sounds a little awkward. So, use his initials...









...no, I can't claim that one as original, but I have no idea who originally came up with it!

He succumbed at last to a little jolt when he got what he thought was a microvolt.

Rather than explain this chart to somebody, could someone develop a fitting so I could check the air pressure in their head first? I would save a lot of sequential (rather than non-sequential) time units that way. Attaching the unit via the ear or nostrils would be preferential.
Could someone market a laminated pocket card of this? It looks more difficult to use than a dummy load. Slightly.

This is awesome. I can already see other applications. What about a Centigrade to Celcius conversion? Why just stop at units? What about a valves to tubes converter or a condensors to capacitors converter? The possibilities are endless.

I wonder if there would be any interest in a program to convert Morse code to CW?

You want a laugh? About 5 years ago, I heard a couple of hams (in the EXTRA portion of the 40M band) discussing 100 feet of RG-17 cable that one of them had purchased at a local hamfest swapmeet. They agreed that because with an Ohmmeter, it didn't measure 50 Ohms, it was defective! (I would have been more than happy to "dispose of it" for them!!) Unfortunately, I didn't have 40 M privileges at the time.

WN3VAW is dead on right. Stimetz was the first with A.C. I guess we can use STZ's as a measure of frequency! By the way does anybody know Kennith!

Edison actually was the first with a Tube diode.
Edison for some reason decided to put a random electrode in a bulb. He measured a voltage at this electrode. He had no idea how this voltage related to the lighting voltage of the bulb. He did not have a clue and gave up.
However it is called the edison effect.
Edison also saw no future another one of his inventions. Moving picture's. Can you picture that! Edison also was a biggot. So Meyer and Golden bought the invention.
Edison thought these just off the boat immigrants could not make his moving picture machine turn a profit. Hey we are all paying up to $10 to see a new movie. I guess Edison may have been a little short sighted!

The following will not rise to the level (depth) of other responses and may lead to headaches, but here goes:

Such a conversion chart will require much more information than the terms baud and bits per second. Such a chart would be quite complex. But wait there's more --

While a popular misconception holds that baud and bits per second are equivalent, they are measures of totally different things. There are countless references that support this, and there are almost as many, perhaps more, that continue the confusion of baud with bits per second. While a number of multi-page descriptions, with math, are available, the explanation from "Newton's Telecom Dictionary" pp. 232-133 (Flatiron, New York: 1994) is fairly concise. Besides Harry is a funny guy (that's an understatement):

"Baud Rate: A measure of transmission speed over an analog phone line [or other such system, W5HFS] -- i.e. a common POTS line. (POTS stands for Plain Old Telephone Service). Imagine that you want to send digital information (say from your computer) over a POTS phone line. You buy a modem. A modem is a device for converting digital on-off signals, which your computer speaks, to the analog, sine-wave signals your phone line "speaks." For your modem to put data on your phone line means it must send out an analog sine wave (called the carrier signal [Does this sound familiar? W5HFS]) and change that carrier signal in concert with the data it's sending. Baud rate measures the number of changes per second in that analog sine wave signal. According to Bell Labs [OK, this was written in 1994, and things have changes at Bell, ATT, Lucent... W5HFS] the most changes you can get out of a 3 KHz (3000 cycles per seccond [where we started! W5HFS] voice channel (which is what all voice channels are} is theoretically twice the bandwidth, or 6,000 baud.

"Baud rate is often confused with bits per second, which is a transfer rate measuring exactly how many bits of computer data per second can be sent over a telephone line. You can get more data per second -- i.e. more bits per second -- on a voice channel than you can change the signal. You do this through the magic of coding techniques, such as phase shift keying. Advanced coding techniques mean that more than one bit can be placed on a baud, so to speak. To take a common example, a 9,600 bit per second modem is, in reality, a 2,400 baud modem with advanced coding such that four bits are impressed on each baud. The countinuing development of newer and newer modems point [sic, W5HFS] to increasingly advanced coding techniques, bringing higher and higher bit per second speeds. My latest modem, for example, is 28,800 bits per second [1994,W5HFS]."

While some would argue with the finer details of Newton's description (I think the concept of "rate" is included in "baud" so "baud rate" is probably not quite the best usage), his presentation of the general concept is helpful.

More technically accurate descriptions are in Sherman: "Data Communications" pp. 7-9, 52-53 (Reston, Reston, VA; 1985) and Bates & Gregory: "Voice and Data Communications Handbook" pp. 281-285 (McGraw-Hill, New York; 2000). Bates & Gregory is especially interesting to hams for its clear description of modulation methods, AM, FM, Phase, QAM.

Examples of Internet references:

http://en.wikipedia.org/wiki/Baud

http://www.webopedia.com/TERM/B/baud.html

After all that take two beers and don't call me in the morning.
