| 释义 | nanosecond (once / 95318 pages) n There are one billion nanoseconds in one second. In other words, a nanosecond is one billionth of a second. Even a blink lasts longer than that. One nanosecond compares to a second the same way one second compares to 31.71 years. It's such a tiny amount of time that it's almost impossible to imagine. Some scientists call a nanosecond a "light foot," since light can travel approximately one foot in one nanosecond. You can also use this word figuratively, to mean "a really short length of time." Nano- comes from the Greek root nanos, "a dwarf." WORD FAMILYnanosecond: nanoseconds USAGE EXAMPLESA nanosecond is one billionth of a second.
