## How fast is a jiffy?

In astrophysics and quantum physics a jiffy is, as defined by Edward R. Harrison, the time it takes for light to travel one fermi, which is approximately the size of a nucleon. One fermi is 10−15 m, so a jiffy is about 3 × 10−24 seconds.

## Why is it called a millisecond?

1/100th of a second is a centisecond, but no one use that. … It isn’t, a millisecond is 1/1000th of a second. Mille means 1000, as in millennium, millimetre, millipede, million. Cent means 100 as in century, centipede, centimetre, dollars and cents.

## How fast is a Yoctosecond?

One yoctosecond is one trillionth of a trillionth of a second (10–24 s) and is comparable to the time it takes light to cross an atomic nucleus.

## What is smaller than a nanosecond?

PicosecondA nanosecond is 10⁻⁹ second (a billionth of a second). Smaller than that: Picosecond.

## What is a Zeptosecond?

A zeptosecond is a trillionth of a billionth of a second. That’s a decimal point followed by 20 zeroes and a 1, and it looks like this: 0.000 000 000 000 000 000 001.

## What is 1/100th of a second called?

1 centisecondStrictly speaking, it is correct to say that one hundredth of a second = 1 centisecond as explained below although the word “centisecond” is rarely used in common language.

## What is the largest unit of time?

supereonThe largest unit is the supereon, composed of eons. Eons are divided into eras, which are in turn divided into periods, epochs and ages.

## What is the shortest measure of time?

Scientists have measured the shortest unit of time ever: the time it takes a light particle to cross a hydrogen molecule. That time, for the record, is 247 zeptoseconds. A zeptosecond is a trillionth of a billionth of a second, or a decimal point followed by 20 zeroes and a 1.

## How long is a second?

Since 1967, the second has been defined as exactly “the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom” (at a temperature of 0 K).

## How small is a Yoctosecond?

A yoctosecond (ys) is a septillionth of a second or 10–24 s*. Yocto comes from the Latin/Greek word octo/οκτώ, meaning “eight”, because it is equal to 1000−8. Yocto is the smallest official SI prefix. A yoctosecond is the shortest lifetime measured, so far.

## How do you convert Jiffies to seconds?

To clarify the math behind MarkR’s answer: sysconf(_SC_CLK_TCK) will get you jiffies per second . Divide jiffies by the number you get from sysconf(_SC_CLK_TCK) to get the total number of seconds.

## Is an attosecond faster than light?

A research team at the University of Central Florida has demonstrated the fastest light pulse ever developed, a 53-attosecond X-ray flash. … At one-quintillionth of a second, an attosecond is unimaginably fast. In 53 attoseconds, light travels less than one-thousandth of the diameter of a human hair.

## Is a moment 90 seconds?

A moment (momentum) was a medieval unit of time. … Although the length of a moment in modern seconds was therefore not fixed, on average, a moment corresponded to 90 seconds.

## What is the fastest second?

An attosecond is 1×10−18 of a second (one quintillionth of a second).

## Is nanosecond the smallest unit of time?

Scientists Have Just Measured The Shortest Unit Of Time Ever. A millisecond is a thousandth of a second, and a nanosecond is a billionth of a second, but there’s another measurement of time that makes both of them look slow.

## Which is the smallest unit?

cellThe cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life. Some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.

## How many nanoseconds are in Eon?

Definition: In relation to the base unit of [time] => (seconds), 1 Nanoseconds (ns) is equal to 1.0E-9 seconds, while 1 Aeons (eon) = 3.1536E+16 seconds.
