Chiliogramma
E Vicipaedia
Imago exemplaris Lutetiae conservati. Non est photogramma sed imago machina computatrali facta, quod nemo chiliogramma publicum videre nec tangere potest.
Chiliogramma,[1][2][3][4] (-atis, n. [2][4]; -atos, n. [4]) sive kilogramma[2][5] (-atis, n. [2]; -ae, f. [2]) est mensura massae et una ex septem principalibus physicae mensuris.
Definitio[recensere | fontem recensere]
Prisca[recensere | fontem recensere]
Unum chiliogramma (1 kg) fuit massa quae in uno litro aquae apud temperaturam IV graduum Celsii continetur. Chiliogramma est etiam 1000 grammata (hoc est, gramma est millensima pars chiliogrammatis).
Hodierna[recensere | fontem recensere]
De anno 1889 1 kg est, per definitionem, massa quae continetur in exemplari prisco apud Officinam Internationale in Pondera et Mensuras Lutetiae sito. Exemplar metallis platino (90%) atque Iridio (10%) factum est. In forma cylindri 39mm alti, cum radio 19.5mm fusum est.
