By the middle of the 19th Century, one of the biggest obstacles still confronting the development of natural sciences, and particularly physics, was the absence of a uniform system of defined measuring units. However, it was not until 1902 that Kelvin could assert that the international system of electrical units was the same in most modern countries and that all their instruments were founded on the centimetre and the gramme.
