Mass: (Kütle) (m) Mass is the quantity of matter it is a scalar quantity measured by equal-arm balance
It is formed of the total number of molecules or atoms of the body.
The mass of an object is constant. It has the same value everywhere.
On the earth, on the moon, at any other planets.
The unit of mass is kg in SI system.
1kg = 1000gr
The mass of any object is given as
M = d*V (density*volume)
Weight (Ağırlık): (W)
There is force acting on this object because of gravity and it is toward the center of the earth. It is called weight.
It is given as,
/W=m*g/
g is the gravitational acceleration.
g = 9.8m/s2 in SI system
The unit of weight and the unit of force are same. [W] = [F] = Newton in SI system
(Weight it the force exerted on the earth by the object)
The magnitude of gravity changes slightly from one planet to other. On the surface of the earth it gets smaller then at points having high altitudes.
In regions of space far from the earth where gravity is zero objects mould have no weight.

If anyone has gone to a car website and looked under the specifications, they'll probably notice that there is usually a weight listed for the car in lbs, then you'll see in parentheses (kg) for kilograms. Since they are saying weight, would the conversion to kilograms be incorrect and shouldn't it be Newtons?
