Very interesting #science news - the first SI prefixes since 1991 were announced today at the General Conference on Weights and Measures.
quetta = ronna = ronto = quecto =
For example the mass of an electron is just under one quectogram (1qg).
The resolution (in French) is available here https://www.bipm.org/documents/20126/64811223/Resolutions-2022.pdf/281f3160-fc56-3e63-dbf7-77b76500990f
@filipw That's amazing! I honestly only knew til exa/atto. Does the document say the reason for adding further prefixes? I'm thinking because of the scale of computing power but maybe there are more?
@bojohn apparently it's driven primarily by data science but I can imagine it useful in other areas such as astro- or quantum physics were things are very large or very small. There is more context in today's article at Nature https://www.nature.com/articles/d41586-022-03747-9
@filipw interesting, thanks for the reference!
@filipw Gonna need them real soon, if things keep on like this...
@steve the quantum state of the latest IBM Osprey quantum processor is a 2^{433} dimensional vector in the Hilbert space. big number... 
@filipw I think we're going to need a bigger boat.
@filipw something to add to the Core Scientific Data Model #CSDM, @pjgrandinetti
@filipw Soon, really large hard drives will come with some spare RiBs …
@filipw It's not only in French: the English version starts page 19 of the pdf
@fgrosshans ah you are right! I stopped at page 7 once I saw the important stuff 
@filipw hmmm. I wonder when total DNA bases will get to the ronnabase level
The resolution in English follows after the one in French half way through that document:

I here by declare October 30, 10^30, to be “Quetta Day” !
(At least in the US; our date system allows for much bigger numbers 
.)
Re “the mass of an electron is just under one quectogram (1qg).”
Actually mₑ = 9 x 10⁻²⁸ g ≈ 10⁻²⁷ g = 1 rontogram. (You might have been starting from the kilogram.)
