Weight In most modern scientific work, physical quantities are measured in SI units. The SI unit of weight is the same as that of force: the newton (N) – a derived unit which can also be expressed in SI base units as kg·m/s 2 (kilograms times meters per second squared).

Pound (mass) Pound (mass) The pound or pound-mass is a unit of mass used in the imperial, United States customary and other systems of measurement. A number of different definitions have been used; the most common today is the international avoirdupois pound, which is legally defined as exactly 0.453 592 37 kilograms, and which is divided into 16 avoirdupois ounces.

In 1661, the Royal Commission of Scotland recommended that the Troy stone be used as a standard of weight and that it be kept in the custody of the burgh of Lanark.

SI Units: Mass SI Units: Mass. The kilogram is the SI base unit of mass and is equal to the mass of the international prototype of the kilogram, a platinum-iridium standard that is kept at the International Bureau of Weights and Measures (BIPM) .he SI unit of mass is the kilogram (kg). In science and technology, the weight of a body in a particular reference frame is defined as the force that gives the body an acceleration equal to the local acceleration of free fall in that reference frame.

Force The SI unit of force is the newton (symbol N), which is the force required to accelerate a one kilogram mass at a rate of one meter per second squared, or kg·m·s−2. The corresponding CGS unit is the dyne, the force required to accelerate a one gram mass by one centimeter per second squared, or g·cm·s−2.

weight When the unit pound is used to indicate the force that a gravitational field exerts on a mass, the pound is a unit of weight. Mistaking weight for mass is tantamount to confusing the electric charges on two objects with the forces of attraction (or repulsion) between them.

Pounds Conversion The pound is a measurement of mass used in the imperial system, and is accepted on a day-to-day basis as a unit of weight (the gravitational force acting on any given object). Definition: The imperial (avoirdupois, or international) pound is officially defined as 453.59237 grams.

Weight In commercial and everyday use, the term weight is usually used to mean mass, and the verb to weigh means to determine the mass of or to have a mass of. Used in this sense, the proper SI unit is the kilogram (kg).

- Mass is the measure of inertia that an object has. Contrary to popular belief, mass and weight are two different terms. Weight refers to the net gravitational force exerted on… an object, with an SI unit of Newtons, while mass refers to the ability of the object to resist changes in velocity, or acceleration.

- NB: kg are actually units of mass (the units of force are N = Newtons, where the force on a 1 kg weight at sea level = 9.8 N). The weight (or force) exerted by a given mass depends on how close it is to the earth’s gravity, so here sea level is assumed.

Stone (unit) The stone or stone weight (abbreviation: st. ) is an English and imperial unit of weight or mass now equal to 14 avoirdupois pounds (6.35029318 kg).ith the advent of metrication, Europe's various stones were superseded or adapted to the kilogram from the mid-19th century on. The stone continues in customary use in Britain and Ireland for measuring body weight, but was prohibited for commercial use in the UK by the Weights and Measures Act of 1985.

If kg is unit of mass, then what's the SI unit of weight? The SI unit of force is Newton. Weight is the result of a mass experiencing the force of gravity, so for all intents and purposes, the SI 'unit of weight' is also Newtons. It is interesting that Newtons are not a fundamental unit, they are derived from a combination of base units. (kG * meters / second ^2).
