Note: Mass and weight are often used, in a general way, as interchangeable terms, since the weight of a body is proportional to its mass (under the same or equal gravitative forces), and the mass is usually ascertained from the weight. Yet the two ideas, mass and weight, are quite distinct. Mass is the quantity of matter in a body; weight is the comparative force with which it tends towards the center of the earth. A mass of sugar and a mass of lead are assumed to be equal when they show an equal weight by balancing each other in the scales. [1913 Webster]
