What does the weighing scale we use in our homes actually measures? As weight should be in Newton and it measures in Kilograms so does it measures our mass ? Why we say that our weight is x Kilograms when we should say the weight is x Newtons , it is too confusing for me .

On Earth, there is little difference between saying your weight vs your mass, because the force of gravity is pretty well constant across the surface. So while the scale is directly measuring weight, it’s as trivial as dividing by 9.8 to give you mass in kilograms.

Mass has no unit and it represents the amount of material in something.
Weight of an object is the force acting on it due to gravity and is defined as mass * force of gravity. And on earth we use lbs, kg, stone, etc. But you could also use newtons.
Newtons is a force where 1 newton is the force required to accelerate 1 kg by 1 m/s/s.

When we measure weight in X kilograms, what we *mean* is a force of X kilograms times the force of Earth’s gravity. 1 kilogram weight is 9.8 kg m/s^2 in force, i.e., 9.8 Newton. This is the force exerted by gravity on an object with a mass of 1 kg.
Since humans mostly live on the surface of the Earth, where the force of gravity is very close to constant, we can measure mass by measuring weight for most purposes.
