[change] Measuring Weight
The weight of a thing can be measured with a scale. The weight is a number showing how much the earth pulls the matter. The number needs a unit of measurement to be useful. The unit of weight used in science and engineering is the Newton, which is actually a unit of force. This is because weight is nothing more than a force.
