Say hello to the first new SI prefixes since 1991. At the humongous end of the scale, ronna and quecca now denote 10 27 and 10 30, respectively. Apparently, the mass of the Earth is six ronnagrams, or ...

Austin Sendek, a University of California-Davis physics undergraduate, promotes a new scientific prefix — the hella.

Capitalization: Prefixes for multiples generally use uppercase symbols (except k, h, da); submultiples use lowercase; Usage: Applied to all SI units (meters, grams, seconds, etc.) and commonly used in ...

Physics & Mathematics Groundbreaking atomic clock is off by less than 1 second every 100 ... The new prefixes were voted in by scientists at the 27th meeting of the General Conference on Weights ...

Meet the metric system’s newest prefixes: ronna-, quetta-, ronto- and quecto-. Adopted November 18 at the 27th General Conference on Weights and Measures in Versailles, France, ronna- and quetta ...

The new prefixes ronna and quetta refer to the largest numbers, while ronto and quecto apply to the smallest. Ronna is a 1 followed by 27 zeroes, and quetta is a 1 followed by 30 zeroes.

Yotta (24 zeroes) was the largest prefix in the metric system before the new additions. Now, the Earth's mass can be said to be about 6 ronnagrams rather than 6,000 yottagrams.

The new prefixes can simplify how we talk about some pretty big objects. "If we think about mass, instead of distance, the Earth weighs approximately six ronnagrams," which is a six followed by 27 ...

A physics student is petitioning the International System of Units to declare "hella" the official designation of 10 to the 27th ... Many numbers have such prefixes, such as "centi" for 0.01 ...

The prefixes make it easier to express large amounts -- for example, always referring to a kilometre as 1,000 metres or a millimetre as one thousandth of a metre would quickly become cumbersome.
