Weight is measured in which unit?

Weight is a measure of the force exerted by gravity on an object. It specifically quantifies this force and is therefore measured in units that reflect this. The correct answer, Newtons, is the unit of force in the International System of Units (SI).

One Newton is defined as the force required to accelerate a one-kilogram mass by one meter per second squared. This definition ties the concept of weight directly to gravitational force, emphasizing that weight is dependent on both the mass of an object and the gravitational acceleration it experiences.

The other choices, such as grams, pounds, and kilograms, refer to units of mass rather than weight. Grams and kilograms are metric units of mass, while pounds are used primarily in the imperial system to measure mass, though sometimes loosely applied as a measure of weight. However, weight must be expressed in terms of force, making Newtons the correct choice for measuring weight in scientific contexts.
