One pound-force is 4.4482216152605 N, so 10 N displays as 2.24809 lbf. One kilogram-force is 9.80665 N, standard gravity times one kilogram.
Kilograms and pounds as mass are on the weight converter. This page does not convert how heavy something is in kilograms.
Kilogram-force is not a kilogram
A kilogram-force is the weight of one kilogram under standard gravity, 9.80665 N. The mass itself is still 1 kg on the weight page.
Dynes
One dyne is 0.00001 N. It is the centimetre-gram-second unit and is in the list for lab values.
Worked example: 10 newtons
From newtons to pounds-force, 10 N displays as 2.24809 lbf. One kilogram-force is 9.80665 N.
\[ 10\,\mathrm{N}=2.24809\,\mathrm{lbf} \]
