International Standards Body Adopts Ronna and Quetta as Newest Metric Prefixes
The international standards community officially adds ronna and quetta to describe massive numbers, providing new terminology for data science and planetary measurements.
The international standards community officially adds two new metric prefixes for extremely large and small numbers. Delegates at a recent conference in Paris vote to adopt ronna for 10 to the 27th power and quetta for 10 to the 30th power, marking the first addition of magnitude indicators since 1991.
To cover the opposite end of the spectrum, the standards body also introduces ronto for 10 to the negative 27th power and quecto for 10 to the negative 30th power. These new units provide convenient shorthand for existing measurements, meaning Earth's mass is roughly one ronnagram and the mass of an electron is about one quectogram.
This expansion proves crucial for the future of data science, as global data production is expected to reach one yottabyte per year in the 2030s. The official adoption prevents unofficial terms like "hellabytes" and "brontobytes" from taking hold in the tech industry, ensuring a standardized approach as digital data scales continue to grow.
