We typically denote numerical values in scientific notation with a number in the interval $[1,10)$, multiplied by a power of ten, followed by a combination of the following units:
| time | second | s , sec |
|---|---|---|
| length | meter | m |
| mass | kilogram | kg |
Occasionally, the power of ten is indicated by one of the following abbreviations
| d | dezi | $10^{-1}$ | |||
|---|---|---|---|---|---|
| c | centi | $10^{-2}\qquad\qquad$ | h | hekto | $10^2$ |
| m | milli | $10^{-3}\qquad\qquad$ | k | kilo | $10^3$ |
| $\mu$ | micro | $10^{-6}$ | M | mega | $10^6$ |
| n | nano | $10^{-9}$ | G | giga | $10^9$ |
| p | pico | $10^{-12}$ | T | tera | $10^{12}$ |
| f | femto | $10^{-15}$ | P | peta | $10^{15}$ |
