1 newton is equal to how many kgs?

Question

some body is telling 1 n = 10 kg, and others telling 9.81 kg and some people telling 100kg. confirm which is right

Answer 1

A Newton is a unit measure of force.
The force is a result of the interaction between two masses.
So the weight of a mass has different values depending on the strenght of the gravity field. On Earth the average gravity field is 9.8 m/s.^2
So in that field a mass of 101.9716 gr would weight one Newton.Note that on an airplane at high altitude the weight of the same mass would be less.

Answer 2

9.81N/kg (not kg/N) is a good approximation on earth. You may be thinking of 1 G. On earth 1 G is 9.81N/kg which means a body of mass is accelerated with 9.81 m/s^2.

So G is actually different from planet to planet. Also as the earth is not a perfect sphere G is actually slightly different from location to location. For really exact and important calculations G will have to be measured for that specific location while 9.81 is a good average value.

Answer 3

F = ma

m = F/a

for gravitational force g = 9.81 and m = 1/9.81kg

Answer 4

A unit of force equal to the force that imparts an acceleration of 1 m/sec/sec to a mass of 1 kilogram; equal to 100,000 dynes (gram)

Answer 5

1 Newton = 0.101 kilogram

Answer 6

1KG=9.81N On earth's gravitational field
