Commonly used prefixes for powers of 10 used with metric units are given below in Table 1.1.
Power | Prefix | Abbreviation |
10- 9 | nano | n |
10- 6 | micro | |
10- 3 | milli | m |
10- 2 | centi | c |
10- 1 | deci | d |
103 | kilo | k |
106 | mega | M |
For Example:
a) 60,000 m = 6 x 104 m = 60 km
b) 0.003 s = 3
x 10- 3 s = 3 ms
