In science and engineering, the weight of an object is usually taken to be the force on the object due to gravity.
In Newtonian physics the weight is a measure of the magnitude of the reaction force exerted on a body.
The weight is the product of the mass of the object and the magnitude of the local gravitational acceleration.
(In a different gravitational field, for example, on the surface of the Moon, an object can have a significantly different weight than on Earth).
