Four new "prefixes" added by International Authorities

How small a number can exhaust the microscopic world? International System Day has introduced four new prefixes for constituting decimal multiples and fractions, expanding the counting of maximum and minimum digits, respectively, in response to the need for scientific advances and increased data storage
.

According to a report by National Public Radio on the 19th, the four new prefixes are ronna, quetta, ronto and quecto
.
Among them, ronna means 27 zeros after the number, and quetta means 30 zeros
after the number.
Ronto and quecto are used to represent very small numbers, with 27 zeros and 30 zeros
after the decimal point, respectively.

The 27th International Conference of Weights and Measures held in Paris, France, adopted the suggestion of Richard Brown, head of metrology at the British National Physical Laboratory, to introduce the above four prefixes to the international system, effective
immediately.
This is the first time since 1991 that the international system has been added
.

Brown told The Associated Press that people are already familiar with the prefix "millimeter" in "millimeter" and "milligram", and the new four prefixes can represent the maximum and smallest data
that has been measured so far.

Previously, the largest prefix in the international system was "yotta", which means 24 zeros
after the number.
Previously, the mass of the Earth could be described as about 6,000 yograms, and after the introduction of ronna, it could be described as about 6 ronnagrams; The mass of the Sun can be described as about 2 billion yograms, and today it can be described as about 2,000 quettagrams
.

The UK's National Physical Laboratory issued a statement saying that data science and digital storage have developed so far, and the existing international maximum count has been used, so it is necessary to introduce new prefixes
.
Brown said the newly introduced prefixes will meet future counting needs
.
The US market research firm International Data Corporation predicts that by 2025, the world will produce 175 zettabyte of data
.
Zetta is the second largest prefix before, indicating 21 zeros
after the number.

The new prefixes ronto and quecto, which denote very small numbers, meet the research needs
of quantum science and particle physics.
Previously, "yocto" was the smallest prefix, and the mass of an electron could be described as about 0.
001 yoktogram, but now it can be described as 1rontogram
.

Brown said ronna and quetta are abbreviated as R and Q, respectively, while ronto and quecto are abbreviated as r and q
, respectively.

He said that Ronna, quetta, Ronto and Quecto were chosen as new prefixes because only the letters R and Q had not yet been used as prefixes, and the four words sounded like Greek pronunciations and satisfied the convention
of ending with a A for large words and o for small words.
