For example, length is defined to be 1.0 meter, a wall is 2.0 meters high, we know that the height of the wall is twice the fundamental unit of length. Likewise, if our fundamental unit of mass is defined as 1.0 kilogram, and we are told that a person has a mass of 75 kilograms, then that person has a mass 75 times as great as the fundamental unit of mass. In 1960, an international committee agreed on a standard system of units for the fundamental quantities of science, called SI (Système International). Its units of length, mass, and time are the meter, kilogram, and second, respectively. Lengt h Definition of the meter One ten-million of the distance from the Earth’s equator to pole the meter was the official length of the meter either In 1960, was the distance between two defined as 1, 650, 763.73 lines on a specific bar of platinum-iridium alloy stored wavelengths of orange-red under controlled conditions. light emitted from a krypton86 this definition was abandoned also This standard was abandoned for several reasons In October1983, the meter was redefined as the distance traveled by light in vacuum during a time interval of 1/299 792 458 second. This latest definition establishes the speed of light at 299 792 458 meters per second . Mass Definition of the kilogram The SI unit of mass, the kilogram, is defined as the mass of a specific platinum-iridium alloy cylinder kept at the International Bureau of Weights and Measures at Sèvres, France Definition of mass at high velocity mass is a quantity used to measure the resistance to a change in the motion of an object. It’s more difficult to cause a change in the motion of an object with a large mass than an object with a small mass. When dealing with atoms and molecules, we usually use the (atomic mass unit) 1 u = 1.6605 *10^-27 kg Time Definition of the second the second, was defined to be (1/60)(1/60)(1/24) 1/86 400 of the average solar day. This standard was abandoned for several reasons The second is now defined as 9 192 631 700 times the period of oscillation of radiation from the cesium atom.
