For the Record, It's 1 kHz, Not 1000 kHz

Tired of seeing this posted on the forum. 1000khz = 1mhz and nobody can hear that high.

When referring to audible sounds.
Correct: 1 kHz
Correct: 1000 Hz
Incorrect: 1000 kHz

moderator edit: fixed khz -> kHz and hz -> Hz

 

Indeed. People need to remember that kilo means thousand, so 1000 khz is actually one million hertz. No one can hear such a frequency. This reminds me when people say theyre 1.80 cm tall Units and prefixes are important, guys

 

Actually, it's kHz and MHz. This is not nitpicking; the use of upper/lower-case can change the meaning.
For example: mHz is millihertz, while MHz is megahertz.

if I could hear all the way up to 20000 khz, then I'd expect that cell towers might actually be a problem for me

 

Cool. So....what is that in metric?

 

Yeah looks like I was wrong, oh well. Never could figure out why they capitalized the H.

 

It's the same. Frequencies are not measures in different units, so there's no metric/imperial difference here.
It think it only applies to length, area, temperature, volume and mass.

Well, the main point you were making wasn't about capitalization. So you weren't all wrong

 

I always wondered about that. Thanks for clearing it up.

 

I know....I was just being a smartarse...

 

That's easy to say, now that I've explained it to you
