Ronnagram:
“If we think about mass, instead of distance, the Earth weighs approximately six ronnagrams,” which is a six followed by 27 zeroes, Brown said. [“Earth now weighs six ronnagrams: New metric prefixes voted in,” Daniel Lawler, Phys.Org]
Quetta is another 3 zeroes, and ronto and quecto down at the other end of the spectrum, describing painfully small measurements. WaPo’s article, “The Earth now weighs 6 ronnagrams. What does that mean?” appears to be terminally confused about the difference between weight and mass:
The Earth can now be said to weigh about six ronnagrams, instead of 6,000 yottagrams. Jupiter can be described as having a mass of about 1.9 quettagrams, instead of just 1.9 million yottagrams. And an electron’s weight is one rontogram, or 0.001 yoctograms.
Mass, not weigh, please. Confusion runneth over. It was probably an ankylosaurus. He was in the club, after all.
