A newton is defined as 1 kg⋅m/s 2 (it is a named derived unit defined in terms of the SI base units). [1]: 137 One newton is, therefore, the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in the direction of the applied force.
newton (SI unit) N A force capable of giving a mass of one kilogram an acceleration of one metre per second per second. ... ≡ 13 595.1 kg/m 3 × 1 mm × g 0 ≈ 1 ...
Newton's second law states that force equals mass multiplied by acceleration. The unit of force is the newton (N), and mass has the SI unit kilogram (kg). One newton equals one kilogram metre per second squared. Therefore, the unit metre per second squared is equivalent to newton per kilogram, N·kg −1, or N/kg. [2]
The tonne-force, metric ton-force, megagram-force, and megapond (Mp) are each 1000 kilograms-force. The decanewton or dekanewton (daN), exactly 10 N, is used in some fields as an approximation to the kilogram-force, because it is close to the 9.80665 N of 1 kgf. The gram-force is 1 ⁄ 1000 of a kilogram-force.

Under Sir Isaac Newton's 338-year-old laws of motion and an important formula that sprang from his work, F = ma, an object with a mass, m, of one kilogram accelerates, a, at one meter per second per second (about one-tenth the acceleration due to Earth's gravity) [4] when acted upon by a force, F, of one newton.
In Germany, the kilopond lost its legal status as a unit of force on 1 January 1978, when for legal purposes the SI unit system was adopted. [3] A kilopond can be converted to the SI unit newton by multiplication with the standard acceleration g n: 1 kp = g n ⋅ 1 kg = 9.806 65 kg⋅m⋅s −2 = 9.806 65 N
