1. The quality of being heavy; that property of bodies by which they tend toward the center of the earth; the effect of gravitative force, especially when expressed in certain units or standards, as pounds, grams, etc.
Note: ☞ Weight differs from gravity in being the effect of gravity, or the downward pressure of a body under the influence of gravity; hence, it constitutes a measure of the force of gravity, and being the resultant of all the forces exerted by gravity upon the different particles of the body, it is proportional to the quantity of matter in the body.
2. The quantity of heaviness; comparative tendency to the center of the earth; the quantity of matter as estimated by the balance, or expressed numerically with reference to some standard unit; as, a mass of stone having the weight of five hundred pounds.
For sorrow, like a heavy-hanging bell,
Once set on ringing, with his own weight goes. --Shak.
3. Hence, pressure; burden; as, the weight of care or business. “The weight of this said time.”

[He] who singly bore the world's sad weight. --Keble.
4. Importance; power; influence; efficacy; consequence; moment; impressiveness; as, a consideration of vast weight.

5. A scale, or graduated standard, of heaviness; a mode of estimating weight; as, avoirdupois weight; troy weight; apothecaries' weight.
