What does "K" means?? B737
 
Hi..
Im a beguiner in this forum, and it is very intersting

I have some doubt about the number that indicates the power of the B737-NG

An 27K engine. What does mean the "K"
Its the same of "pounds" or something eles??

Thanks

27000 lbs thrust i would think.

Euclidessn 30th Mar 2009 21:42
Right, but what exactly "K" instead of "Lbs" ?? :ok:

Rainboe 30th Mar 2009 21:44
K means thousand.

Rigga 30th Mar 2009 21:51
Kilogramme = 1000 grammes
Kilometer = 1000 meters

Euclidessn 31st Mar 2009 00:51
:confused: I dont understand that logic, because we can have 1 kilogrammes and 100 kilogrammes, 1000 kilogrammes and so on :confused::confused:

What do one thing have to see with another one???

G'day Euclidessn,

The letter 'K' is the standard metric abbreviation for one thousand, I'm sure you already know this. 1 kilogram being 1000 grams, 100 kilograms being 100,000 grams etc.

The abreviation you mentioned
An 27K engine
is a little incorrect in that it doesn't state the unit of measurement but in the aviation industry it is accepted to mean a 27,000lbs thrust engine.

Regards,
BH.

I always thought that the "K" was a spin off of the resistor code 470,000 Ω or 470 kΩ....

Maybe yes or maybe no?

jxk 31st Mar 2009 06:00
Just to confuse things even more in computer terms K is = 1024 (2**10)
As in 1 KB = 1024 bytes:-)

Dual ground 31st Mar 2009 06:33
I would hazard a guess that it is only in the last 20 to 30 years that a 27,000lb thrust engine has become known as a 27K engine? The increased use and commonality of PC's has meant that the use of K to represent 1000 has now become widespread. As for K coming from the resistor colour code that comment is slightly skewed. The resistor clolor code uses k as that is the Scientific Notation for 10*3, as Mega (M) is SN for10*6, Giga (G) 10*9and Tera (T) 10*12 etc.

To technical people there is a difference: k (lower case) is the SI prefix for 1000 while K (upper case) is the computer geeks abbreviation for 1024.

BUT since the eighties it has gradually leaked from technical jargon to a more widespread use by normal people, so that today you see job ads mentioning a salary of "50K". Non technical people informally use K (upper case) to mean 1000.

'K'onfusing!
 
Just to add another sausage in the pan.

K or 'Kay' is often used by sportsmen to abbreviate distance. As in 'a ten kay cross country' (XC) run/glider flight/cycle ride etc. :\

Have to admit though that having been in aviation for most of my life it's only in the last couple of years that the term 'k' has become common slang for gas turbine thrust rating. Certainly in this part of the world. :ok:

Hey People...
Thanks every body
Very intersting the explanations. Now I understand the relation between K and 1000 :ugh:

I am a 737-700/800 NG - SFP beginer co-piloto in Brazil :E.... and no one here know how to correctly answer me

I did quote 2 of more intersting explanation, but I thanks for all answers.
Soon I will bring another questions

Thanks again :ok:

Nobody training you knew? This doesn't bode well.......

We have good professionals here.
I didnt ask for every one, just for one or another person, one or another pilot.
Ive never asked it to an instructor, in fact :ok:

HAWK21M 12th Apr 2009 04:40
23K = 23 x 1000 = 23,000lbs of thrust.

Did you actually bother reading the rest of the posts in this thread? :ugh:
