Since Monday, the measurement system changes and there will be a new kilogram

May 18, 2019

The new measure was approved in November 2018 in France.

On Monday the new definition of the kilogram will be implemented: the kelvin, the ampere and the mole. The measure was approved last November during the General Conference of Weights and Measures, France.

The day that takes effect everywhere in the world redefinition of the International System of Units, the National Institute of Industrial Technology (INTI), will do a day on the science of measurements. It has not been changed since 1960.

The meeting will focus "on this question will be the key in the future for the accurate administration of drugs"Especially," in the pharmaceutical industry, measuring climate change, computing, electronics, among many other sectors that work with great precision, "said the agency on its website.

On World Science Day, they mobilize against the adjustment

"All units will be defined on the basis of constants of nature. Instead of artifacts, material properties or theoretical experiments unachievable, as it was the case until now, "said Héctor Laiz, head of metrology and quality at NRTIs.

However, they specified that "this will not have an impact on the scale that the doctor uses to weigh a patient, but will have a great repercussion for the scientific field"

And they added: "The biggest change will likely be felt by manufacturers of scientific instruments, who will have to adapt their products to the new measures."

How does science contribute to making us more beautiful?

It will also be "essential for better climate change predictions, as more accurate measurements can be made to monitor small temperature variations".

According to Mr. Laiz, this change "will also be a challenge for education because we will now have to teach high school students the new definitions of units of measurement".

The INTI expert is the only South American representative on the International Committee of Weights and Measures who was in charge of the revision. The Free day at Migueles Technological Park of INTI, located in San Martín, between 21h and 13h.
