Weight v. t. : 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.

Weight v. t. : 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.

Weight v. t. : Hence, pressure; burden; as, the weight of care or business.

Weight v. t. : Importance; power; influence; efficacy; consequence; moment; impressiveness; as, a consideration of vast weight.

Weight v. t. : A scale, or graduated standard, of heaviness; a mode of estimating weight; as, avoirdupois weight; troy weight; apothecaries' weight.

Weight v. t. : A ponderous mass; something heavy; as, a clock weight; a paper weight.

Weight v. t. : A definite mass of iron, lead, brass, or other metal, to be used for ascertaining the weight of other bodies; as, an ounce weight.

Defination from the web:
weight of an object is the magnitude, W, of the force that must be applied to an object in order to support it (i.e. ... The weight of an object equals the magnitude of the gravitational force acting on the object, less the effect of its buoyancy in any fluid in ...
