 Weight - Wikipedia, the free encyclopedia
Under most circumstances, this ambiguity is not a problem, because the weight of an object is directly proportional to its mass, and the constant of proportionality -- the strength of the gravitational field -- is approximately constant everywhere on the surface of the Earth (around 9.8 m/s²).
Although terms such as "atomic weight", "molecular weight", and "formula weight" may still be encountered, such usage is often discouraged; terms like atomic mass are used instead.
The weight force that we sense is actually the normal force exerted by the surface we stand on, which prevents us from being pulled to the center of the Earth, and not the weight itself.

For example magensium chloride has the formula unit MgCl2, i..e., for every magnesium cation there are two chloride anions in the crystal.
Therefore, to get the formula weight of an ionic compound we need simply determine the molar atomic mass of a formula unit.
Or, we would say that the formula weight of MgCl2 = 95.211 g/mol (i.e., 95.211 g of magnesium chloride has a mole of magnesium cations and 2 moles of chloride anions.

 Federal Bridge Law - Hendrickson International
The weight of the longer vehicle is spread out, while the shorter vehicle has all of the weight concentrated on a small area.
The result is that motor vehicles may be loaded to the maximum weight only if each group of axles on the vehicle and their spacing also satisfy the requirements of the Formula.
Bridge Formula calculations yield a series of values usually referred to as Bridge Table B. However, the single-axle weight limit replaces the Bridge Formula weight limit on axles not more than 40" apart, and the tandem-axle weight limit replaces the Bridge Formula weight limit for axles over 40 but not more than 96 inches apart.

Although it is uncertain whether intentional weight loss increases longevity [7], it is well documented that losing weight improves health [8] and quality of life [9].
For the first 4–8 weeks the declines in weight appear to be similar at both levels of caloric restriction but between weeks 12 and 20 the difference between the 1200 and 1500 calorie allocation for the first 12 weeks seems to be reflected in a greater weight loss for the more aggressively restricted group.
This 40-week weight loss trial comparing two distinct patterns of caloric restriction indicated that, on the whole, both protocols were associated with fairly similar magnitudes of beneficial weight loss, as well as similar beneficial changes on health variables.
