The avoirdupois system
The avoirdupois system (abbreviation for the avoirdupois system is avdp.) is a measurement system of weights that uses pounds and ounces as units. It is used in United Kingdom, Canada, New Zealand, Australia, and some other former British colonies, despite their official adoption of the metric system.
The avoirdupois system was used for the first time in the 13th century and was updated in 1959. That time the international pound and yard were the subject of an agreement among representatives of six nations signed on 1 July 1959: the United States, United Kingdom, Canada, Australia, New Zealand, and South Africa. The agreement defined the (avoirdupois) pound as exactly 0.45359237 kilograms and the yard as equal to 0.9144 meters and the.
Advp vs metric system
Currently that system of weights is used in the United States. In varying degrees, in everyday life in the United Kingdom, Canada, New Zealand, Australia, and some other former British colonies. For that system distances are given in meters and kilometers and weight in grams and kilograms.
How many stones – basic info about st
Some basic definitions about stones and pounds were provided in the article 47 kg in stone. Here we can mention that stone (abbreviation is st) is British unit of weight, equal to 14 pounds avoirdupois (6.35 kg).
In the past stone weight varied from 4 to 32 pounds which is equivalent of 1.814 kilos to 14.515 kilos. It used to be also compared to a rock selected as a local standard and that type of stone came to be widely used as a unit of weight in trade. For exemple in the 14th century England’s exportation of raw wool to Florence necessitated a fixed standard. In 1389 a royal statute fixed the stone of wool at 14 pounds and the sack of wool at 26 stones.
Currently the stone measurement is still commonly used in Britain to designate the weights of people and large animals.
How many pounds – basic info about lbs
Pounds (abbreviation is lbs) are units of mass derived from the Roman libra. It’s worth to mention that the pounds are also items of force and a monetary ones used in many countries, for example in: UK, Egypt, Sudan, Syria and Lebanon.
Both stone and pounds are part of British measurement system called imperial system defined as measurement used in Great Britain and former British colonies. In addition, it has been used traditionally in sea and air transport. For weight measuring we can use not only stones (st) and pounds (lbs) but also grain (gr), drachm (dr), ounce (oz), quarter (qr or qtr), hundredweight (cwt), ton (t) or slug (slug).
Just to define only few and provide some conversions:
1 ounce equals one sixteenth of pound and according to SI measurement it’s also equal to 28.349523125 g.
A drachm is 1/16 of an ounce and according to SI formula it’s 1.7718451953125 g.
Main truth about the system, called also metric decimal system is as. follows: it’s set of systems of components of measurement with basic items: meter as the principle of length and kilogram as the value of mass. A principal rule of creating multiplicity of that items bases on a formula: multiplying the one by the integer (positive or negative) power of ten.
In the past (mid XIX century), when this system was not fully followed by societies, James Clerk Maxwell introduced the concept of a coherent system in which a small number of items of measurement were defined as base portions and all others, called derivative items, were defined in terms of base ones. Maxwell proposed three base ones – length, mass, and time. Between 1850 and 1900, there was rapid progress in the use of this system. It has been adopted all over Europe (except Great Britain), in Latin America, as well as in many countries on other continents. This became a key phrase for the development of science.
How to convert 83 kg to stone
83 kg in stone can be easily converted. Let’s check conversion to metric values first.
83 kg to g = 83 kg x 1000 = 83000 g
83 kg to dag = 83 kg x 100 = 8300 dag
83 kg to t = 83 kg : 1000 = 0.083 t
For imperial converter, to answer how many stones (st) but also how many lbs, you can base on below logic.
83 kg in stone (st) = 13.07 st
83 kg in pound (lbs) = 183 lbs
83 kg in ounces = 2928 oz
83 kg in drachms = 46844 dr
1 st = 6.350293 kg
1 pound = 0,4536 kg
