This question is asking us about one femtosecond and specifically how to relate one femtosecond to one second. Brown already has names at the ready: bundecca and bundecto, based on the Latin for 11, undecim.Which of the following is equal to one femtosecond when multiplied by one second? One times 10 to the 15, one times 10 to the negative 15, 10 times 10 to the nine, 0.1 times 10 to the negative nine, one times 10 to the negative 12. If those four are approved, Brown says, only a single good letter would remain that could be used on its own for 10 33 and 10 − 33 in future: B (and b). "Once people start using the wrong prefix names it is impossible to go back," he says. Emilio Prieto, who represents the Spanish Metrology Center in Madrid on the units committee, says he would vote for the names because they are simple and memorable. Ronna, quecca, and their partners could fare better. It lasted 7 minutes before being deleted. One prankster hacked a Wikipedia article in 2008 to introduce a new technical term for a computer that could attempt 10 48 operations per second: a gonnaflop. (Contrary to reports, the idea did not reach the BIPM units committee for formal discussion.) In 2008, an article in The New York Times on supercomputers referred to a xeraflop, and a 2015 paper on cosmic engineering used the symbols X, W, and V to describe the gargantuan energy levels, beyond the yotta scale, that could be seen if aliens turned a black hole into a particle accelerator. In 2010, a physics student in California suggested "hella" as a prefix for 10 27, and thousands of people signed an online petition in support. Other proposals to extend the measurement scale have fizzled. "It would be premature to mention a possible outcome of the discussion," she wrote in an email. It's too early to say whether the prefixes will be adopted, says Estefanía de Mirandés, executive secretary of the units committee and a physicist with BIPM.

The organization's general conference, which includes government representatives and is due to next meet in 2022, would have the final vote-as it did late last year when it approved a new definition of the kilogram based on fundamental physical constants. If the committee approves the idea, it could make a formal recommendation to BIPM. The terms are due to be discussed at the October meeting of BIPM's Consultative Committee for Units.

Metrologists are proposing to extend metric prefixes beyond yotta and yocto. "It's supposed to be a conversation starter," says Brown, who published his proposal last month in the journal Measurement. And so, drawing from the Latin and Greek words for nine ( novem, ennea) and 10 ( decem, deka), with some poetic license to make the terms more easily pronounced, he came up with ronna, quecca, ronto, and quecto. He also wanted to continue the reverse alphabetical trend set by zetta and yotta, but needed to avoid letters such as X, W, and V that could be confused with other terms. The new prefixes should relate etymologically to nine and 10, to represent the ninth and 10th powers of 10 3. Although mathematicians sometimes use the prefix googol (10 100), a name coined a century ago by a 9-year-old girl, it, too, is unofficial.īrown prefers to follow tradition. He says unofficial terms beyond yotta, including brontobyte and geobyte, are already becoming popular.

"Where there is a need that is not met, there is also a risk that unofficial units can take hold and that can cause confusion," says Richard Brown, head of metrology at the National Physical Laboratory near London, who came up with the new names. Much smaller and they run out of metrological road. At the other end of the scale, quantum physicists have measured atomic forces as small as 42 yoctonewtons. Without new prefixes, computer scientists will have no way to officially talk about what comes next. The planned update responds to the massive growth in global data storage, which by the early 2030s is forecast to reach 1 yottabyte (10 24)-the top of the existing scale. They would be the first prefixes added since 1991. If approved, the new terms could be formally introduced in 2022. They would be joined by their microscopic counterparts, ronto for 10 − 27, and quecto for 10 − 30. Fresh from redefining the kilogram and other fundamental measures, the guardians of the metric system have set their sights on another upgrade: new prefixes for outrageously large and small numbers.Ī proposal lodged with the International Bureau of Weights and Measures (BIPM) in Paris recommends new names-ronna and quecca-as prefixes for 10 27 and 10 30, respectively.
