What Does KN Stand For In This Description...

This description describes the engines available for the 767-400. There is something I do not understand however:

Two 281.6kN (63,300lb) Pratt & Whitney PW4062 turbofans, or two 276.2kN (62,100lb) General Electric CF6-80C2B7F1s or 282.5kN (63,500lb) CF6-80C2B8Fs.


Is "kN" some sort of metric measurement?

What does it stand for?

What formula does one use with the 281.6kN to get 63, 300 pounds of thrust?


Thanks to all that respond.

kN= kilonewtons

Newtons are the standard Metric measure of force, unless I'm mistaken. (I took physics 4 years ago, cut me some slack if I'm wrong!)

You are not wrong.

A Newton is indeed the standard Metric measure of force, and as such, it has units of kg*m/s^2.

One Newton is equal to 0.225 lbs. So to convert to lbs:

(281.6*1000)*0.225 = 63,360 lbs.



I'm watching Jeopardy. The category is worst Madonna songs. "This one from 1987 is terrible".
