Weight Description

In science (physics) weight – is the measurement of the gravitational pull on an object or the amount of force of gravity acting upon it. The term weight is different than mass although they can be confused and used interchangeably in daily life. Mass depends on how much matter there is in an object or material, it is an intrinsic property and is measured in kilograms. The mass of a body is a set value and this means it is the same no matter where it is located, but the weight can change with the change of location as it depends on the force exerted on the object. The actual official unit for measuring weight is Newton, other units for measuring weight are pound-force

In places with zero gravity, the objects still have mass but have no weight. This is why for example astronauts in space stations must exert force to push themselves off the walls or pull themselves around and along. And the bigger their mass, the more force it will take for them to move around.

This category is called Weight but is actually meant in its synonymous use for mass and the reason for it is that in everyday situations the word “weight” is utilized when “mass” is actually meant.

Common (and not so common) units used to measure mass, but usually expressed as weight in daily life are: gram, kilogram, metric ton, pound, ounce, microgram, carat, quintal (or centner, hundredweight), slug, stone, grain, pennyweight, tael (Chinese unit), arroba (Portuguese and Spanish custom unit of mass, weight or volume). The troy weight system of units of mass is used to measure precious metals and gemstones and it includes troy ounce, troy pound, pennyweight, troy grain, mint weights or moneyers' weights (which splits into grains, mites, droits, and perits).
