    Its the SI unit of force equal to the force required to accelerate 1kg at 1 g (9.8m/s^2).

    Is it not the force required to accelerate a 1kg mass at 1m/s^2?

    Yes, 1 Newton of force will accelerate a mass of 1 Kg at 1 m/s^2.

    The kilogram is sometimes used as a measure of weight, mostly outside the realm of science; 1 kg weight being equivalent to 9.8 newtons. As far as SI units go, a mass of 1 kg weighs 9.8 newtons, newtons being the SI unit of force/weight. That's on earth, of course.
