# How Long is a Century?

Besides, to know about the century decade, people won’t get the perfect answer about how long is a century?  In this article, we elaborate all the related information about a century, its periods and decade period. In the representation of 100 years, we might say that a century referred to a bike ride of 100 miles.  But if you are taken this assumption in metric centuries than the results are different from this assumption.

This is because the metric centuries are shorter than the previous century. Let we explain this with the use of the same example that if you are taking 100 years, then the metric century can be referred to the bike ride of 100-kilometers. These both situations can be considered by the different relative cycles of the single day. Most of the people taken these results for granted but some people thoroughly conclude all the findings to find out the exact answer of how long is a century.

## Calculating the time:

In between the state of hours in the saddle, the period depends on some factors which are available in our environment. With the previous example, the resulted time depends on these factors which include wind direction, the speed of the wind, Cyclist strength, and other factors. It stated that a century is passing explicitly in one second at a time of expansion. Some of the mathematicians report that few of us lives this complete journey in a bit time which is less approximately to the calculated results. The resultants output equals to 3.16 billion seconds in one go.

## What is a century? Facts and figures:

People want to know about that how long is a century? A century equaled to 100 years. The century means that it is an arbitrary period of 100 years.  There are two viewpoints and standards of centuries. One view based on the on the strict constructions and the other hand the second standard based on the general usage (popular perspective). In these two perspectives, people will get the exact idea of how long is a century with two different ideas and concepts. With strict construction in the 1st-century start with the 1 AD and its ends with 100 AD. The related pattern goes with the same order in onward.

## Centennial year:

In the previous strict construction model, the ninth century will start on the year calculated with formula (100 x n) – 99 and it ends with (100 x n). Due to this reason the century can only include one year. This year is known as the centennial year. The centennial year starts with every century number. In the second standard which is known as general usage, the centuries related to the decades. This alignment is formed by grouping many years by digits. In this second model, the ninth century will start with the year calculated with formula (100 x n) – 100, and it ends with (100 x n) – 1. The outgoing results show like odometer effects.  The first century starts with the year number zero rather than beginning with one year.
