Redefining the Kilogram

Posted on May 9, 2019

On Monday May 20th the change in definition of the kilogram goes into effect. For the last 129 years, the kilogram has been defined as the mass of a hunk of platinum-iridium alloy that’s been housed at the International Bureau of Weights and Measures in Sèvres, France since 1889. In November scientists from sixty nations around the world voted unanimously to redefine the kilogram to be based upon the Planck constant. As aerospace engineer Max Fagin stated, “The SI unit system will finally be a truly universal system, free of any human artifacts.”

Our cohorts at Sartorius went in depth with a white paper detailing what the redefinition of the kilogram means for weighing technology users. Read it here.
