A nanosecond is to one second, as one second is to approximately 31.69 years. A nanosecond is equal to 1000 picoseconds or 1 / 1000 microsecond . Time units ranging between 10 −8 and 10 −7 seconds are typically expressed as tens or hundreds of nanoseconds.

10 times the length of the previous cosmological decade, with CD 1 beginning either 10 seconds or 10 years after the Big Bang, depending on the definition. eon: 10 9 yr: Also refers to an indefinite period of time, otherwise is 1 000 000 000 years. kalpa: 4.32 × 10 9 yr: Used in Hindu mythology. About 4 320 000 000 years. exasecond: 10 18 s ...

10 microseconds (μs) – cycle time for frequency 100 kHz, radio wavelength 3 km. 18 microseconds – net amount per year that the length of the day lengthens, largely due to tidal acceleration. [3] 20.8 microseconds – sampling interval for digital audio with 48,000 samples/s. 22.7 microseconds – sampling interval for CD audio (44,100 ...
Milliseconds and microseconds are particularly common. Prefixes for multiples of a second are rarely used: ... 31.7 years (or 31 years, 252 days, 1 hour, 46 minutes ...
A picosecond is to one second, as one second is to approximately 31,688.76 years. Multiple technical approaches achieve imaging within single-digit picoseconds: for example, the streak camera or intensified CCD (ICCD) cameras are able to picture the motion of light. [1] [2] One picosecond is equal to 1000 femtoseconds, or 1/1000 nanoseconds.
It is also the standard single-unit time representation in many programming languages, most notably C, and part of UNIX/POSIX standards used by Linux, Mac OS X, etc.; to convert fractional days to fractional seconds, multiply the number by 86400. Fractional seconds are represented as milliseconds (ms), microseconds (μs) or nanoseconds (ns ...
