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 .

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.
