补充回答：OED李关于它的历史1. a. A unit of mass (formerly also taken as a unit of weight) that was introduced as a fundamental unit of the metric system and is now one of the base units of the International System of Units, being equivalent to approximately 2·205 lb.; it was intended to be the mass (or weight) of a cubic decimetre of distilled water, but in practice has been defined almost from its inception as the mass of a unique physical standard (orig. the ‘Kilogramme des Archives’, and since 1889 the International Prototype of the Kilogramme). 1797 Jrnl. Nat. Philos. I. 197 The kilogramme [is] equal to 2 pounds 5 gros 49 grains. 1810 Naval Chron. XXIV. 299 The French weight called Kilogramme. Ibid. 301 Killogram (weight of cubic decimeter of water). 1825 J. Nicholson Operat.

Arnold-Forster (title) The Coming of the Kilogram, or the Battle of the Standards. 1946 Proc. R. Soc. A. CLXXXVI. 171 The kilogram was originally defined by reference to a ‘natural’ standard, i.e. the mass of the cubic decimetre of water. The material representation of this standard was the Kilogramme des Archives, a simple cylindrical piece of platinum which was constructed in the latter part of the eighteenth century. 1964 H. S. Hvistendahl Engin. Units iii. 20 Study of the archives of the BIPM [sc. the Bureau International des Poids et Mesures] has shown that whilst due to the lack of precision in scientific terminology at that time, the word ‘poids’ (weight) was improperly used as a synonym of ‘mass’, the kilogramme étalon was definitely intended to represent the unit of what we now always call mass, and not the force by which that mass unit was attracted to the earth. 1969 Changing to Metric Syst. (Nat. Physical Lab.) (ed. 3) 5 The spellings of the units of length (metre) and mass (kilogramme) given above are those used by the General Conference of Weights and Measures.

An object having a mass of one kilogram and made as a standard of mass or weight. 1831 Jrnl. R. Inst. Gt. Brit. II. 65 The rather unsightly appearance of the standard kilogramme of Monsieur Fortin's making. 1856 Phil. Trans. R. Soc. CXLVI. 875 Permission was obtained from the French Government to compare the pound with the standard kilogramme of platinum deposited in the Archives on the 22nd of June, 1799, known as the ‘kilogramme des Archives’. Ibid. 878 The kilogramme, after having been washed with alcohol, was suspended from the right-hand pan of the balance. 1922 Nature 19 Oct. 622 During the nineteenth century+serious doubt arose as to whether the accepted standard kilogramme [sc. the ‘Kilogramme des Archives’ made by Lefèvre-Gineau and Fabbroni in 1799] actually did comply with the original definition of the kilogramme.+ A proposal to construct a new standard kilogramme brought the whole subject under review in 1872, and the Commission Internationale du Mètre+decided that the international kilogramme should be a copy of the ‘Kilogramme des Archives’. 1936 Rep. Board of Trade Standards Dept.
