The standard unit for measuring weight is the Newton (N) in the International System of Units (SI). A Newton represents the force needed to accelerate a one-kilogram mass by one meter per second squared. However, in everyday contexts, weight is often measured in grams or kilograms, particularly for smaller objects. Weight, distinct from mass, accounts for the gravitational force acting on an object. For instance, a person weighing 70 kilograms experiences a weight of approximately 686 Newtons on Earth due to gravity. Understanding these units is crucial in science, engineering, and daily life.
