A nanosecond is shorter than a microsecond. There are one thousand nanoseconds in a microsecond.
A Nanosecond
A nanosecond is shorter than a millisecond
An attosecond is one quintillionth (10 to the power of minus 18) of a second. As of 2006, the smallest unit of time that was directly measured was on the order of 1 attosecond (10−18 s), or about 1026 Planck times. In physics, the Planck time, (tP), is the unit of time in the system of natural units known as Planck units. It is the time required for light to travel, in a vacuum, a distance of 1 Planck length. The unit is named after Max Planck, who was the first to propose it.
Time intervals longer than a second include the minute, hour, day, week, and year. Time intervals shorter than a second include the millisecond, microsecond, and nanosecond. Technically, the second is a metric unit. So, you can add any metric prefix to the second to increase or decrease the amount of time the unit represents.
All and any moment of time that's shorter than a millisecond.
Examples: -- picosecond -- femtosecond -- yoctosecond -- attosecond
One microsecond is one one-millionth of a second, or 0.000001 seconds. Being that it is considerably shorter than a second, the length of a second cannot be contained within this span of time.
heavier isotopes can be produces but their halflives are in the microsecond or shorter range.
1 ms (millisecond, or 1 thousandth of a second) is a shorter time span than 10 ms. So one could say that it is a faster time.
There is no antonym for century. The closest I could come would be a second. A century is a long time (by normal human standards) and a second is a short time. But then, a millisecond is even shorter than a second, and a millennium is even longer than a century, so we do not really have exact opposites here.
One second is 1000 milliseconds; the prefix milli- always refers to one- thousandth
