B Is this person wrong?

Please reference where this statement is taken from.

 

I suggest paying absolutely no attention to that "answer" whatsoever.

 

Because it contains a large number of erroneous statements.

 

Isn't that enough?

You yourself pointed out the discrepancy in the exponents of the "conversion".

I suspect the author's degree will be one of those "self-awarded" B.S. degrees - all B.S., no substance.

 

You have lots of opportunities to learn things you do not know. The internet generally is only a good place to do it if you have reliable resources. Physics Forums has a large amount of knowledgable members and you will often get great answers. We are not a replacement for a textbook though.

 

As pointed out, ignore the article.

You have learned something.
The article has errors.
You have pointed out one error.
Posters are agreeing with you.
Thus, you have learned that your own physics knowledge may be better than that of the author.
Thus, move on from that that article.

A blatant error such as the one below shows that the has author has taken as little as possible effort to get, or to make sure, things are correct.

 

I honestly have a really hard time to imagine how this was the conclusion you drew from my post ...
