What is the unit of measurement for weight?

The correct answer is Newtons, which is the unit of measurement for weight in the International System of Units (SI). Weight is a force that results from the acceleration of gravity acting on mass. Therefore, it is measured in Newtons, which quantifies the force exerted by gravity on an object. One Newton is defined as the amount of force required to accelerate a one-kilogram mass at a rate of one meter per second squared.

While grams is a unit of mass and is often used in contexts involving weight, it does not measure the force of gravity acting on that mass, which is essential in determining weight. Liters are units of volume, used to measure the space an object occupies, and do not relate to weight. Meters are a unit of length, which measure distance rather than weight. Thus, Newtons are the appropriate unit for measuring weight due to the relationship between mass, space, and the gravitational force acting on objects.
