The kilogram-force (kgf or kgF) is a gravitational metric unit of force. It is equal to the magnitude of the force exerted by one kilogram of mass in a 9.80665 m/s2 gravitational field - Wiki
i mean ,the earths gravity which is 1 Newton = which is 9.8 m/s^2,so so a 0.98kg of mass /0.98Kilogram-force would have `9.8 newtons of force,if i am right?
Maybe you wrote in a hurry,1 Newton is not equal to 9.8m/s^2. Newton is a unit of force.
1 Newton = 1kg * 1 m/s^2 = 1kg-m/s^2.
1 kgf is equal to the magnitude of the force exerted by one kilogram of mass in a 9.8 m/s2 gravitational field.
So, a 0.98kg of mass exerts 0.98 kgf or in equivalent terms 0.98 * 9.8 = 9.604 N.
1 kgf = 9.8 N , 0.98 kgf = 9.604 N
