Kilogram is a unit of mass. Newton is a unit of force. Totally different. A pound, on the other hand, can be EITHER a unit of mass OR a unit of force.
A pound of force is not "equal" to a pound of mass. And a kilogram does not "equal" 9.8 Newtons. Here on earth, an object with a mass of one pound happens to have a weight of one pound. Once you leave the earth's gravity, that's no longer true. Likewise, a one kilogram mass weighs 9.8 Newtons on earth, elsewhere in the universe it's something else.
Why does a kilogram mass weigh 9.8 Newtons? Because a Newton is the amount of force required to accelerate a one kilogram mass at one meter per second squared. F=ma. In order to make F=ma work in with English units, you have to throw in a conversion factor, because a pound of force is NOT the same thing as a pound of mass.
