Prefixes and Magnitudes
To make sense of the vast range over which physical quantities are measured, prefixes are used as a short-cut to writting the magnitude using scientific notation
| Prefix | Magnitude |
|---|---|
| atto a | 10-18 |
| femto f | 10-15 |
| pico p | 10-12 |
| nano n | 10-9 |
| micro μ | 10-6 |
| mili m | 10-3 |
| Kilo k | 103 |
| Mega M | 106 |
| Giga G | 109 |
| Tera T | 1012 |
| Peta P | 1015 |
| Exa E | 1018 |
Other prefixes which are commonly used but are not strictly part of the SI system.
| Prefix | Magnitude |
|---|---|
| centi c | 10-2 |
| deci d | 10-1 |
| Deca Da | 101 |
| Hecto h | 102 |
