What is Picosecond?
A '''picosecond''' is a [[SI unit|standard unit]] of measuring time. It is equal to 10<sup>−12</sup> of a [[second]]. It is one trillionth, or one millionth of one millionth of a second, or 0.000000000001 seconds. One picosecond contains 1000 [[femtosecond]]s. There are 1000 picoseconds in one [[nanosecond]]. ;Notation * 10<sup>-10</sup> seconds is 100 picoseconds. * 10<sup>-9</sup> seconds is 1 [[nanosecond]]. ;Examples * One picosecond is the [[Half-life (element)|half-life]] of a bottom [[quark]]. * Ten picoseconds after the [[Big Bang]], [[electromagnetism]] became its own [[force]]. * It takes [[Speed of light|light]] about 3.3 picoseconds to travel one [[millimeter]]. * It takes a common 3.0-[[Hertz|gigahertz]] computer 3.3 &times; 100 picoseconds to add two [[integer]]s together. {{Ordersofmagnitudeseconds}} [[Category:Units of time]] [[Category:Orders of magnitude]] {{Math-stub}}
