Jeff Gust, Chief Corporate Metrologist here at Fluke Corporation, breaks down the redefinition of the Kilogram.
The Kilogram was originally defined as the mass of one liter of water at 4 degrees Celsius, the point of which water is most dense. It was replaced by a platinum cylinder artifact in the late 18th Century. The "Le Grand K" has been the World Standard of Mass since 1889.
After decades of groundbreaking laboratory work, the world’s scientific and technical community is about to redefine four of the seven base units for the International System of Units (SI). On November 16, in Versailles, France, representatives from 57 countries are expected to make history. They will vote to dramatically transform the international system that underpins global science and trade.
