How much weighs a kilogram? Scientists seek answer are how much she weighs one kilogram? The question seems silly, but some scientists are still searching for the answer without losing the hope of moving towards a value constant for kg, independent of any physical object. Since 1889, the kilogram is based on a cylinder made up of 90% Platinum and 10% Iridium, manufactured in London in 1879 and preserved under a bell jar in the Office of weights and measures in Sevres, near Paris. The measurements made over a hundred years ago show that kg has thinned. Its mass has changed the equivalent of a grain of sand from 0.4 mm in diameter. Enough to allow scientists from around the world to study a definition that will pass the physical object, just as they did with you meter, now defined by the speed of light. The objective is to redefine all basic units – mass, distance, time, etc.-with stable and universal values.

For kg, scientists suggest the use of the Planck, a value as constant It is named after the father of quantum physics, Max Planck. Complex for the neophyte, the Planck constant is defined with a formula called h. remains to define the relationship between the kilo of lifetime and Planck’s constant. For this reason, experiments are underway around the world. Scientists use balances of Watt, a device that allows you to convert the mechanical power into electrical power and vice versa. Our experiments are moving, but it is too soon to put into practice the new definition of the kilogram, said Michael Stock, of the Royal Society of London. One of the problems is that we will need more balances Watt that we have to measure reliably the kilogram when the new definition applies, explains. He believed that change could reasonably be adopted in the next Conference of weights and measures scheduled in Paris in 2015. mission to supply our customers efficient procedures that enable us to provide to them, safety and knowledge in the choice of computers and accessories with regard to his laboratory and Instrumentation industry, thus providing solutions early projects in execution referred to in this area.
