Scientists Confirm a New Expanded Scale of Measurement

[Still Waters]

Say hello to ronnagrams and quettameters: International scientists gathered in France voted on Friday for new metric prefixes to express the world's largest and smallest measurements, prompted by an ever-growing amount of data.

It marks the first time in more than three decades that new prefixes have been added to the International System of Units (SI), the agreed global standard for the metric system.

Joining the ranks of well-known prefixes like kilo and milli are ronna and quetta for the largest numbers – and ronto and quecto for the smallest.

The change was voted on by scientists and government representatives from across the world attending the 27th General Conference on Weights and Measures, which governs the SI and meets roughly every four years at Versailles Palace, west of Paris.

FYI there is about 10^18 millimeters in a light year. So a Quecca meter would be a Trillion (10^12) light years across. I think I got that math right....

And the best guess for the Visible Universe is about 100 Billion light years. So our visible universe is 1/10th a Queccameter.
