Conversions of many more force units
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. |
Conversion of newton to kilogram
Not for physic professors and science teachers :-) Only for domestic use on Earth.
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 |
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. |
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. |
