I noticed that the impact force going from pounds force to kilonewtons does not add up in the item description. 4800 lbf should be about 21.4 kN, not 7.2 kN. So what is the correct breaking strength for this cord, 21.4 kN or 7.2 kN?

The impact force of a rope refers to what the force of impact would be on a climber if he/she took a fall of factor 1.77. Therefore the figure would mean the impact force would only be 7.4kN. Whether this number is actually correct or not, I have no idea...

lbf and kN are both units of force. I would guess it is a typo. From Sterling Ropes website, the mean breaking strength is 4271 lbf/19.0kN http://www.sterlingrope.com/product/299384/A060PC%20cordelette/_/6mm_PowerCORD_Cordelette

That is a good question. Usually the tensile (static) strength is in lbf. and the breaking (dynamic) strength is in kN. Since this is a static cord the breaking strength is weaker because this should be used only for static conditions (anchors, etc). I think i am right, hope this helps!
