Conversions of force  units F 
Newton is the SI basic unit of force 1 N = 1 kg × m / s2
The unit sign is N and the symbol of force is F (force)
Force of weight FG = m × g; mass = m and gravity acceleration g = 9.80665 m/s2
The gravitational force is the force type in everyday life we constantly have to do.

Fill in the appropriate line the known force value.

The question: "What is the weight of one kilopond? (kilogram force kgf)" is easy to answer.
The kilopond is old and of no use. Do not think about it: One kilopond = 1 kp weighs exact 1 kilogram = 1 kg.
In 1960 the force unit kilopond was changed to newton in the SI system. 1 kp = 9.80665 N.
1 kg on the surface of the Earth weighs 9.80665 N, because 1 kg × 9.80665 m/s = 9.80665 N.

In daily life on Earth we take:
1 newton (force) ≈ 1/9.80665 kg = 0.10197 kg ≈ 102 grams (weight).
1 kilonewton (force) = 1000 N ≈ 1000/9.80665 kg = 102 kg (weight).

Our physics teacher always said to us:
One Newton is a bar of chocolate.
102 gram ≈ 1 Newton.

Weight is a) the force to a body in a gravitational field as the weight force,
                b) the mass of a physical body.

The force conversion formulas
Newton to kilogram-force (N to kgf):
1/9.80665 × N = 0.101971621298 × N = 1 kgf
Kilogram-force to newton (kgf to N):
9.80665 × kgf = 1 Newton N
Since 1977 kgf and kilopond (unit symbol kp) are no longer the permissible unit of force. It was formerly a base unit of the Technical measurement system. Correct is now only N (pronounced Newton).
1 kilogram force (kgf) was the force of gravity, which is pushing a mass of 1 kg at one place in the world on the ground; calculated according to Newton's law force = mass × acceleration. Since the acceleration is dependent on the location, the weight force is varying. Usually, however, the standard acceleration of gravity is used. 1 kgf = 9.80665 newtons.
