Historic Vote Ties Kilogram and Other Units to Natural Constants Versailles, France—A convocation of delegates representing 60 countries voted today in Versailles to implement the most...

Auditing standard for management system standards now updated Management systems help organizations achieve their objectives, and auditing them makes good business sense. The International Standard for auditin...

SI Redefinition This November, 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. This single action will finally realize scientists’ 150-year dream of a measurement syste...

Though he had little formal education, Michael Faraday made invaluable contributions to our understanding of electromagnetism. He was born this week in 1791. The SI unit of capacitance, the farad, is named after him.

Scientists Have Devised a Revolutionary Way to Redefine the Kilogram Researchers have come up with the most precise determination of Planck's constant ever, making it possible to reframe the idea of what a kilogram even is.

The latest episode of Veritasium features NIST's efforts to redefine the kilogram using our Kibble balance! View it here: https://youtu.be/Oo0jm1PPRuo

Ready for Take-off, Thanks to Million-Pound Deadweight Machine How a three-story stack of stainless steel makes sure your jet's wings do what they do best. The wings on an airliner, such as the Boeing 787 shown above, are subject to huge forces. But how do plane manufacturers know for sure how much force their wings will bear? They can measure them with sensors...

Georg Ohm was born this week in 1789. He discovered that the voltage applied to a conductor is proportional to the resulting electric current, which is now known as Ohm’s Law. In addition to the law, Ohm is also the namesake of the SI unit of resistance. Read more about how resistance, voltage and current are measured in the SI: https://www.nist.gov/pml/weights-and-measures/si-units-ampere. Happy birthday, Georg, and happy !

Happy and happy holidays!

Units of measure are getting a fundamental upgrade New units based on fundamental properties of the universe will make measurements more precise.

Our units of measurement are finally about to get an upgrade By the end of 2018, a kilogram will no longer exist as we know it, with our standard units of measurement finally scheduled to get a much-needed upgrade for the first time in more than 50 years.
