A nanosecond (ns or nsec) is one billionth (10-9) of a second and is a common measurement of read or write access time to random access memory (RAM). ... A microsecond (us or Greek letter mu plus s) is one millionth (10-6) of a second. A picosecond is one trillionth (10-12) of a second, or one millionth of a microsecond.
How many zeros does a nanosecond have?
One nanosecond is 10-9 seconds, or one billionth of a second. This means that there are one billion nanoseconds in one second; one billion is one followed by 9 zeros.
How is nanosecond measured?
A nanosecond (ns) is an SI unit of time 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 prefix nano- with the basic unit for one-sixtieth of a minute. A nanosecond is equal to 1000 picoseconds or 1⁄1000 microsecond.
