What is the name given to the largest unit of time? Units of Time
Eons, or Eonothems, are the largest division of time, lasting thousands of millions of years. There eons are: the Phanerozoic (current eon) and the Precambrian eons of the Proterozoic, Archean, and Hadean. Eras, or Erathems, are the subdivisions of eons.
What is the longest measure of time? – Additional Questions
What is the least and largest unit of time?
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. The only unit of time shorter than a zeptosecond is a yoctosecond, and Planck time. A yoctosecond (ys) is a septillionth of a second.
Is there a Centisecond?

What is bigger than a Yottasecond?
Petasecond is one quadrillion seconds. Exasecond is one quintillion seconds. Zettasecond is one sextillion seconds. Yottasecond is one septillion seconds.
Is parsec a unit of time?
Unfortunately, like the similarly misused ‘light-year’, the parsec is a unit of length, not of time. A parsec is equal to about 3.26 light-years or roughly 31 trillion kilometres (19 trillion miles). The unit has its origins in one of the first methods of determining the distance to the stars.

What is the metric unit of time?
Metric time is the measure of time intervals using the metric system. The modern SI system defines the second as the base unit of time, and forms multiples and submultiples with metric prefixes such as kiloseconds and milliseconds.

What is the order of metric units from smallest to largest?
Here are the common metric units of length from smallest to largest.
- A millimeter is the smallest unit. Millimeters are most useful when measuring really tiny things.
- A centimeter is the next smallest unit.
- A meter is a little more than 3 feet.
- A kilometer is used to measure longer distances.
Which one is bigger cm or mm?
Millimeter A millimeter is 10 times smaller than a centimeter. The distance between the smaller lines (without numbers) is 1 millimeter. 1 centimeter = 10 mm.
