Is one billionth of a second called?
nanosecond
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.
What is 1 millionth of a second called?
A microsecond (us or Greek letter mu plus s) is one millionth (10 -6 ) of a second.

What is smallest than second?
The units smaller than a second are: Milliseconds: 10-3 s. Microseconds: 10-6 s. Nanoseconds: 10-9 s. Picoseconds: 1012 s.
What is the fastest second?
Scientists have measured the shortest interval of time ever recorded, clocking how long it takes a particle of light to cross a single molecule of hydrogen. The ultra-quick journey took 247 zeptoseconds, according to a team of German researchers, with a zeptosecond representing a trillionth of a billionth of a second.
What is smaller than a picosecond?

Picosecond is one trillionth of a second. Nanosecond is one billionth of a second. Microsecond is one millionth of a second. Millisecond is one thousandth of a second.
How long is a Decasecond?
101 seconds
The decasecond (das) is a unit of time in the International System of Units, defined as 101 seconds using the SI prefix system.
Is a picosecond a thing?
A picosecond (abbreviated as ps) is a unit of time formed by the prefix pico- and the SI unit second, equal to 10−12 or 1⁄1 000 000 000 000 (one trillionth) of a second. That is one trillionth, or one millionth of one millionth of a second, or 0.000 000 000 001 seconds.
