I just know all you fellow geeks are out there drooling over the answer to this one, so I won’t keep you waiting.
What’s a sub-second, you ask?
Let’s make this easy…
Sub-Seconds and their Equivalents
a SECOND is 1000 milliseconds
a millisecond is 1000 microseconds
a microsecond is 1000 nano seconds
a nanosecond is 1000 picoseconds
a picosecond is 1000 femtoseconds
a femto second is 1000 attoseconds
an atto second is the shortest measurement of time as of May 12, 2010.
Interesting facts about the attosecond
- 1 attosecond – In this amount of time, light can travel the length of two hydrogen atoms.
- 24 attoseconds – A single unit of atomic time.
- One attosend is to one second as one second to 31.71 billion years.
- The attosecond is the smallest measurement of time man-kind can presently make.
Sub-Seconds to their Negative Powers
- milli = 10^-3
- micro = 10^-6
- nano = 10^-9
- pico = 10^-12
- femto = 10^-15
- atto = 10^-18
