Nanosecond: SI unit of time
A nanosecond (ns) is one billionth of a second.
It is equal to 10−9 seconds.
One nanosecond contains 1000 picoseconds. 1000 nanoseconds is equal to one microsecond. Ten nanoseconds are sometimes called a shake.
Some things that take between one nanosecond and ten nanoseconds are listed below
- Light travels about 29.9 centimeters in 1 nanosecond. That is 3.33564095 nanoseconds to move 1 meter.
- It takes a fusion reaction between 20 and 40 nanoseconds to finish in a hydrogen bomb.
- It takes a nuclear reaction 10 nanoseconds to finish one generation with fast neutrons.
- The half-life of a K meson is 12 nanoseconds.
