Conversions of force units
Units of force conversions F (not weight)

The force F: Newton N is the SI basic unit of force. 1 N = 1 kg × m / s².
The unit symbol is N and the symbol of the force is F (force).
Force of weight is FG = m × g, Mass = m and gravity g = 9.80665 m/s².

 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.

Force is not Mass!

1 N is the force of Earth's gravity on a mass of about 102 g = (1 / 9.81 kg).

 Simply enter the value to the left or the right side. The calculator works in both directions of the ↔ sign.

 The force conversion formulas Newton to kilogram-force (N to kgf): 1 N = 0.101971621298 kgf Kilogram-force to newton (kgf to N): 1 kgf = 9.80665 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.

1 kgf weighs 1 kg on Earth, that is equivalent to 9.80665 N.

 kg is a mass unit and newton is a force unit. Mass is called weight (in non-scientific affairs) F = m × g or m = F / g Gravity of Earth g = 9.80665 m/s² Mass m = 1 N / (9.80665 m/s²) = 1 kg × m/s² / (9.80665 m/s²) = 0.101972 kg = 101.972 g A mass m = 101.972 g has a weight force of F = 1 N.

 Pressure p = F / A (force divided by area), force F = p × A (pressure times area), area A = F / p (force divided by pressure)

 Definition: Kilogram The kilogram or kilogramme, (symbol: kg) is the SI base unit of mass. A gram is defined as one thousandth of a kilogram. Conversion of units describes equivalent units of mass in other systems. Definition: Newton In physics, the newton (symbol: N) is the SI unit of force, named after Sir Isaac Newton in recognition of his work on classical mechanics. It was first used around 1904, but not until 1948 was it officially adopted by the General Conference on Weights and Measures (CGPM) as the name for the mks unit of force.
