Weight

Weight Weight, n. [OE. weght, wight, AS. gewiht; akin to D. gewigt, G. gewicht, Icel. v[ae]tt, Sw. vigt, Dan. v[ae]gt. See {Weigh}, v. t.] [1913 Webster] 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. [1913 Webster]

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. [1913 Webster]

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. [1913 Webster]

For sorrow, like a heavy-hanging bell, Once set on ringing, with his own weight goes. --Shak. [1913 Webster]

5. A scale, or graduated standard, of heaviness; a mode of estimating weight; as, avoirdupois weight; troy weight; apothecaries' weight. [1913 Webster]

A man leapeth better with weights in his hands. --Bacon. [1913 Webster]

7. A definite mass of iron, lead, brass, or other metal, to be used for ascertaining the weight of other bodies; as, an ounce weight. [1913 Webster]
