A nanosecond comes before an attosecond and before a nano second is a millisecond and before that is a second
An attosecond is an SI unit of time equal to 10 ^ -18 seconds.
Attosecond
a zeptosecond
An attosecond is 1x10-18 seconds
Examples: -- picosecond -- femtosecond -- yoctosecond -- attosecond
The smallest type of second is the attosecond, which is one quintillionth (10^-18) of a second. It is used primarily in the field of physics, particularly in the study of ultrafast processes such as electron movements within atoms. To provide context, an attosecond is to a second what a second is to about 31.7 million years.
V - Think keyboard
Split second, milli, micro, nano, pico, femto, attosecond etc.
V comes before B.
a millisecond comes before a second
58622 comes 1 before 58623, 58613 comes 10 before 58623.
T comes before U, and V comes after U.
