A seemingly easy question with a bizarre answer. The gram (1/1000th of a kilogram) is defined as the mass of one cubic centimetre of water at 0˚C, so it seems obvious that a kilogram would simply be the similar measurement of 1000 cubic centimetres of water. Stunningly, however, the kilogram is actually defined as the mass of the International Prototype of the Kilogram, a physical object that’s kept at the International Bureau of Weights and Measures in France.</p> Sun, 14 May 2017 02:30:56 +0000 Ada McVean B.Sc. 2446 at /oss
