The kilogram or kilogramme, (symbol: kg) is the SI base unit of mass. A gram is defined as one thousandth of a kilogram. Conversion of units describes equivalent units of mass in other systems. Klinkenberg, Adrian (1969). "The American Engineering System of Units and Its Dimensional Constant g c". Industrial & Engineering Chemistry. 61 (4): 53–59. doi: 10.1021/ie50712a010. The Greeks used the same weight measurement as the Babylonians, but the Romans changed it. Their basic unit of weight was the 'uncia,' from which the English word 'ounce' is originally derived. The uncia is a twelfth part of the 'pes,' which is the Roman 'foot —' our word inch is also derived from 'uncia.' The Romans used the same word for ounce, which they measured using a technique taken from the Arabs. The International System of Units assigns special names to 22 derived units, which includes two dimensionless derived units, the radian (rad) and the steradian (sr). The kilogram-force ( kgf or kg F), or kilopond ( kp, from Latin: pondus, lit.'weight'), is a non-standard gravitational metric unit of force. It does not comply with the International System of Units (SI) and is deprecated for most uses. The kilogram-force is equal to the magnitude of the force exerted on one kilogram of mass in a 9.806 65m/s 2 gravitational field ( standard gravity, a conventional value approximating the average magnitude of gravity on Earth). [1] That is, it is the weight of a kilogram under standard gravity. Therefore, one kilogram-force is by definition equal to 9.806 65 N. [2] [3] Similarly, a gram-force is 9.806 65mN, and a milligram-force is 9.806 65μN.

Multiplied units often turn up in "double proportion" situations, where a particular quantity is proportional to multiple dependent variables. To take a deliberately non-physics example, a difficult task might need either many people to work on it or people to work on it for a long time, so its difficulty is proportional to both the number of workers and the time spent and could thus be measured in "person-days". A six person-day job would require two people to work for three days to complete it, or three for two days, or whatever. (The validity or otherwise of the model in which these two working schemes are equivalent is left as an exercise for the reader!) Comings, E. W. (1940).

The kilogram is the base unit of mass in the International (SI) System of Units, and is accepted on a day-to-day basis as a unit of weight (the gravitational force acting on any given object). Although there's no precise standard for doorknob heights, they're often about 1 meter above the floor. The International (SI) System of Units published in 1960 used the kilogramme as the base unit of mass, and has been adopted by almost every country on earth (with a few notable the exceptions such as the United States).

Resolution 7 of the 9th meeting of the CGPM (1948)". Archived from the original on 2020-06-22 . Retrieved 2021-03-02. The kilogramme (derived from the Greek chilioi [thousand] and gramma [a small weight] was named as a more practical measure of mass for larger quantities in trade, and came to be used as the base unit of mass in all metric measurement systems. In 1795 metric measurement systems were introduced in France and the gram was defined as "the absolute weight of a volume of pure water equal to a cube of one hundredth of a metre, and at the temperature of the melting ice".This measure has come down to us as part of the British Imperial System of Weights and Measures, which is also used in the U.S. This system of units was first defined in the British Weights and Measures Act of 1824, which was later refined and reduced. The system came into official use across the British Empire. Moving to a fairly exact parallel from a physics context, an electron-volt - or, to be pedantic, an electron-charge-volt - is a good unit of energy because the work done to move a charge through a potential difference is proportional to both the charge and the potential difference. The same goes for a coulomb-volt, although of course we just call that a joule. kgf" redirects here. For other uses, see KGF (disambiguation). "Kilopond" redirects here. Not to be confused with Kilopound. kilogram-force The metric system was not particularly popular in revolutionary France, and Emperor Napoleon, who came just after the Revolution, abolished it. But, when Napoleon lost power, the system was reinstated. Harman, George G. (2010). Wire Bonding in Microelectronics (3rded.). New York: McGraw-Hill. p.408. ISBN 978-0-07-164265-1. OCLC 609421363. Breaking load (BL): The strength of a wire and its actual force (usually given in grams, grams-force, mN, etc.) required to break a particular wire in a tensile pull. It is not tensile strength, which by definition is the force per unit area.

Kilogram-force is a non-standard unit and is classified in the International System of Units (SI) as a unit that is not accepted for use with SI. [4] History [ edit ] It is the only SI unit that is defined by a physical object rather than a fundamental physical property that can be reproduced in laboratories. Some other units such as the hour, litre, tonne, bar, and electronvolt are not SI units, but are widely used in conjunction with SI units. Translated into English as the 'ounce,' King Offa, who lived at the end of the 8th century, accepted the silver ounce but then ran short of silver. The Dirhem was halved to 222 grains for the penny, twenty of which made the ounce as before, and twelve ounces the pound in silver. The kilogram is the weight of one liter of water. One thousandth of a kilogram is a gram. All multiples and submultiples of the base units are in powers of ten. Fractional units are not halves, but tenths, unlike the customary practice for fractions of inches, and derived units are related to the base units by multiples of powers of ten, unlike what is the case with twelve inches making a foot. Basing all units on multiples of ten makes conversion from one unit to another particularly easy.

In 1855, a fire destroyed the Houses of Parliament in London, where the standards for these weights were kept. A standards bureau was set up with prototypes for the imperial system at that time. The Babylonians invented the talent, as the basic unit of weight, and, based on their sexagesimal (60-based), divided into equal parts in terms of that number. Early Babylonian and Egyptian records, as well as the Bible, indicate that weight was originally measured by the capacities of containers such as gourds or clay or metal vessels. These were filled with plant seeds that were then counted to measure the volumes. With the development of scales as a means of weighing, seeds and stones served as standards. For instance, the "carat," still used as a mass unit for gems, is derived from the carob seed. The kilogram-meter per second (kg · m/s or kg · m · s -1 ) is the standard unit of momentum . Reduced to base units in the International System of Units ( SI ), a kilogram-meter per second is the equivalent of a newton-second (N · s), which is the SI unit of impulse. Although the units are the same in base terms, there is a conceptual difference between momentum and impulse.
