How is that 1 kg is equal to one Newton and how can I find it?
Question Date: 2013-01-09
Answer 1:

A kilogram is a unit of mass, which is almost exactly equal to the mass of one liter of water.

The Newton is a unit of force, and it is equal to the amount of net force required to accelerate a mass of one kilogram at a rate of one meter per second squared.

The Newton is named after Isaac Newton in recognition of his work on classical mechanics.

The Newton’s second law of motion states that

F = ma

If you look at the units in this formula, m is mass and it has units of kg; a is acceleration and it has units of meter/s2, therefore you get the Newton as the unit of force.

Force{Newton} = mass {Kg} acceleration {meters/sec2}
