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.]
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.
3. Hence, pressure; burden; as, the weight of care or
business. "The weight of this said time." --Shak.

moment; impressiveness; as, a consideration of vast
In such a point of weight, so near mine honor.
5. A scale, or graduated standard, of heaviness; a mode of
estimating weight; as, avoirdupois weight; troy weight;
6. A ponderous mass; something heavy; as, a clock weight; a

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.
8. (Mech.) The resistance against which a machine acts, as
opposed to the power which moves it. [Obs.]
Atomic weight. (Chem.) See under Atomic, and cf.
Dead weight, Feather weight, Heavy weight, Light
weight, etc. See under Dead, Feather, etc.
Weight of observation (Astron. & Physics), a number
expressing the most probable relative value of each
observation in determining the result of a series of
observations of the same kind.
Syn: Ponderousness; gravity; heaviness; pressure; burden;
load; importance; power; influence; efficacy;
consequence; moment; impressiveness.
