According to Physics language, weight of an object with mass "m" is actually the force experienced by it under gravitional pull by another object(for us, Earth). My mass is approximately around 7.143Kg. And my weight is 70.000N. Why do people say my weight is 70Kg?
Is not It a big flaw?
At which point of time, the degree of misconception did appear in the past?
Dear Muthumanickam Venkatachalam
good question
The Newtonian concept is totally incorrect. The whole law of Newtonian that we use, is wrong.
Newton's law is saying, more mass, more gravity. but that is not true.
If earth had Newton's gravity, earth would never had rain. for more detail.

I think it is because people live on Earth, where the weight is proportional to the mass everywhere. The differences in weight on different places on Earth can normally be neglected. And it would not be possible to introduce "Newton" in daily live, where rules and language should be simple. "1 N" is too abstract, but all know what is "1 kg".There are more such simplifications, e.g. to give acceleration of cars in units like "from 0 to 100 in x seconds" instead of m/s2.
Muthumanickam Venkatachalam :
As Bachelor of Science you should be able to differ between mass (unit kg) and force (N). In colloquial language, this distinction is not made.
Previously, the unit of force was kp and 1kg corresponds to a weight of 1kp.
@Hans-G. Hildebrandt
Sir, I can distinguish the differences. My question was why do we use Kg instead of N. We have standard units, no-one can't change them. understanding N is not difficult for an ordinary citizen. And also we can't disrespect Sir Isaac Newton's work by changing units.
But the exact answer is the weighing machine weighs our weight in N but in return, It displays output in Kg by dividing our weight by "9.8(m/s^2). So, the problem is the name "weight machine" instead It should be a "mass machine". Everything is correct except the name of the machine.
I was not in doubt that you can differ between mass and force!
The mass (in kg) of an object is the same at all points of the universe. Mass is a fundamental property of all material matter.
The weight (in N) of an object varies within a gravitational field and from gravitational field to gravitational field what mean within the universe. Weight (force) appears only in a gravitational field.
Quite straight forward
kg is mass and Newtons a force, the force of gravity exerted on Earth would be greater than the moon for instance.
