As ever more digital data is created and stored, the world needs more unit measurements to keep up with the ever-expanding numbers.

To do so, the 27th General Conference on Weights and Measures on Friday introduced four new prefixes to the International System of Units, or metric system: ronna (27 zeroes after the first digit) and quetta (30 zeroes)…
…(plus two more for very very small decimals).
The International System of Units (SI) has these standardised prefixes (among others):
Power – Prefix
- 103 – kilo
- 106 – mega
- 109 – giga
- 1012 – tera
- 1015 – peta
- 1018 – exa
- 1021 – zetta
- 1024 – yotta
- 1027 – ronna
- 1030 – quetta
