Subdivisions of the day include the hour (1/24 of a day), which is further subdivided into minutes and seconds. The second is the international standard unit (SI unit) for science. Celestial sphere-based: as in sidereal time, where the apparent movement of the stars and constellations across the sky is used to calculate the length of a year.
3.33564095 microseconds – the time taken by light to travel one kilometre in a vacuum. 5.4 microseconds – the time taken by light to travel one mile in a vacuum (or radio waves point-to-point in a near vacuum). 8 microseconds – the time taken by light to travel one mile in typical single-mode fiber optic cable.
nanosecond: ns One billionth of one second 1 ns: The time needed to execute one machine cycle by a 1 GHz microprocessor 1 ns: The time light takes to travel 30 cm (11.811 in) 10 −6: microsecond: μs One millionth of one second 1 μs: The time needed to execute one machine cycle by an Intel 80186 microprocessor 2.2 μs: The lifetime of a muon
A nanosecond (ns) is a unit of time in the International System of Units (SI) equal to one billionth of a second, that is, 1 / 1 000 000 000 of a second, or 10 −9 seconds. The term combines the SI prefix nano- indicating a 1 billionth submultiple of an SI unit (e.g. nanogram, nanometre , etc.) and second , the primary unit of time in ...

The bit time for a 10 Mbit/s NIC is 100 nanoseconds. That is, a 10 Mbit/s NIC can eject 1 bit every 0.1 microsecond (100 nanoseconds = 0.1 microseconds). Bit time is distinctively different from slot time, which is the time taken for a pulse to travel through the longest permitted length of network medium.
In some data communication standards, a time unit (TU) is equal to 1024 microseconds. [1] This unit of time was originally introduced in IEEE 802.11-1999 standard [2] and continues to be used in newer issues of the IEEE 802.11 standard. [1] In the 802.11 standards, periods of time are generally described as integral numbers of time units.
Resolution of 1 ps with a 100 MHz (10 ns) clock requires a stretch ratio of 10,000 and implies a conversion time of 150 μs. [13] To decrease the conversion time, the interpolator circuit can be used twice in a residual interpolator technique. [13] The fast ramp is used initially as above to determine the time. The slow ramp is only at 1/100.
