Officials have approved new prefixes that can be applied to metric system units of measurement The ronna, ronto, quetta, and quecto prefixes are four new prefixes that will enable scientists to define the largest and tiniest entities in the universe.
The use of colloquial words is a result of the speed at which new scientific discoveries are made and the extent to which existing limitations are being pushed. There are several citations to hellabytes and brontobytes (both 1027 bytes), which are unofficial terminology and symbols (‘h’ and ‘b’, respectively), on the internet, which may cause confusion for research projects that use ‘h’ for hecto (102) and ‘H’ for henry (the unit of electrical inductance). Additionally, “B” stands for a belio, a measure of sound intensity, and “b” stands for a barn unit of area (10-28 m2).
Who decided these news units?
The General Conference on Weights and Measures (GCWM)’s conference, which took place from November 15 to November 18 at Versailles Palace outside of Paris, France, saw the adoption of the new prefixes by scientists. According to the CIA, the new words are a component of the International System of Units, also known as the metric method, which is the major measurement system used by every nation in the world except for Myanmar, Liberia, and the United States, which mostly use the imperial system
Where are these new prefixes applicable?
The new prefixes can be used with any of the seven metric base units: grams (g) for weight, meters (m) for length, seconds (s) for time, amps (A) for electric current , kelvin (K), for temperature, moles (mol), for substance amount, and candela (cd) for luminosity and also other units, such as bytes for computing.
One ronto (r) is equal to one octillionth of something (10^minus27 or a decimal point followed by 26 zeros and a 1), whereas one ronna (R) is equal to one octillionth of something (10^27 or 1 followed by 27 zeros). The equivalent of one quetta (Q) is one nonillion of anything (10^30), while the equivalent of one quecto (q) is one nonillionth of something (10^minus30).
Why the addition now?
Since the GCWM approved the addition of the zetta (10621), zepto (10^minus 21), yotta (10^24), and yocto (10^minus 24) prefixes in 1991, no additional prefixes have been introduced to the metric system.
The new names begin with the letters “r” and “q,” which are the only ones that aren’t already designated in the metric system. For huge objects, the final letter is always a “a,” while for little things, the final letter is always a “o.” Because the new prefixes are the 9th and 10th largest and smallest prefixes in the metric system, the remaining words are roughly based on the Greek and Latin words for 9 and 10.
According to members of the U.K.’s National Physics Laboratory (NPL), who spearheaded the effort for the new prefixes, the fundamental justification for the new prefixes is that data science has grown so much that there is now a lot higher need for greater digital storage in computing.
A metrologist at NPL who formally proposed the new units at the GCWM meeting, Richard Brown, told French news agency AFP that “we’re quite close to the limit” in terms of representing data in yottabytes, the largest prefix currently. Computer experts would soon have to start storing the data in ronnabytes and subsequently quettabytes, he continued.
How will the new prefixes affect the system of measurement of space?
According to Brown, the new prefixes for massive things, ronna and quetta, are also the ideal scale to assist astronomers in accurately weighing planets. He said that, for instance, Jupiter weighs about 2 quettagrams and Earth weighs about 6 ronnagrams.
To balance the scales, the prefixes ronto and quecto, which stand for small items, must be used. A symmetrical enlargement makes sense at the bottom end, according to Brown. He said that the new measures might potentially be useful for researchers studying extremely minute objects in fields like particle and quantum physics.
