Have you ever stopped to think why 1kg weighs 1kg? When it comes to measuring units, it’s all down to comparisons. Some parameters are measured against something in nature that’s immutable:
One metre is defined by the distance that light travels in 1/299792458 second.
One second is defined by the precise number of oscillations in the radiation of an atom of cesium-133. In other words, it’s the time that elapses during 9,192,631,770 (9.192631770 x 10 9 ) cycles of the radiation produced by the transition between two levels of the cesium-133 atom.
These and other units of measurement contained within the Metric System, formulated with the help of Antoine Lavoisier back in 1793, during the French Revolution, are utilized by all nations worldwide except for the USA, Myanmar (Burma) and Liberia.
