The kilogram (also spelled kilogramme [1]) is the base unit of mass in the International System of Units (SI), having the unit symbol kg. [1] The word "kilogram" is formed from the combination of the metric prefix kilo- (meaning one thousand) and gram ; [ 2 ] it is colloquially shortened to " kilo " (plural "kilos").
The kelvin is defined by setting the fixed numerical value of the Boltzmann constant k to 1.380 649 × 10 −23 J⋅K −1, (J = kg⋅m 2 ⋅s −2), given the definition of the kilogram, the metre, and the second. mole: mol amount of substance: The amount of substance of 6.022 140 76 × 10 23 elementary entities.
A number of units were used. One libra (lit. "pound") was equal to 0.460 246 34 kg as it was legally defined. [1] Some other units and legal equivalents are given below: 1 tomin = 1 ⁄ 768 libra 1 adarme = 1 ⁄ 256 libra 1 ochava ("eighth") = 1 ⁄ 128 libra 1 onza ("ounce") = 1 ⁄ 16 libra 1 arroba = 25 libras 1 quintal ("hundredweight ...
kilogram: kg mass "The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 × 10 −34 when expressed in the unit J s, which is equal to kg m 2 s −1, where the metre and the second are defined in terms of c and ∆ν Cs." [1]
As with a definition based upon carbon‑12, the Avogadro constant would also have been fixed. The kilogram would then have been defined as "the mass equal to that of precisely 1000 / 196.966 5687 × 6.022 141 79 × 10 23 atoms of gold" (precisely 3 057 443 620 887 933 963 384 315 atoms of gold or about 5.077 003 71 fixed moles).
Kilo is a decimal unit prefix in the metric system denoting multiplication by one thousand (10 3). It is used in the International System of Units , where it has the symbol k , in lowercase . The prefix kilo is derived from the Greek word χίλιοι ( chilioi ), meaning "thousand".
