The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton.

What is the force against weight?

ObjectMass (kg)Weight (N)Pat Eatladee25 kgSee Answer 245 N (or ~250 N if approximating g to be 10 m/s/s)

Is weight and force the same thing?

Weight is a specific force acting on an object due to gravity. Weight is a very specific instance of force: force is the more generalised term, which includes all other causes and influences such as friction, electromagnetism and so on – including weight. Weight is the force associated with gravity.
