# Units of Time

In the topic units of time we have given conversion table. Throughout history, it has been determined by using the reflection of the sun. Stonehenge, constructed over 4000 years before in England, It is used to tell ancient civilizations the time of the day and year.

Ancient people used lunar eclipses, the position of sun, and other seasonal events to determine the time. People used these stones to know the time of the day. In 46 BC Julius Caesar decided that the calendar year should have 365 days, but every fourth year that should have an extra day, which would be called as a "leap year". He adapted this basis because if that particular year was divisible by four then it was to be a leap year. The year can not to be a leap year unless it was divisible by 100 and 400.

world time

1.Local time of any place is 12 noon when the sun is exactly over our head.

2. Standard time is the uniform time fixed by all the countries .

3.Greenwich mean time is the united kingdom time.

4.Indian standard time is fixed on the mean of 82 1/2° east meridian.

5.Eastern Standard time (EST) is 5 hours behind of Coordinated Universal Time (UTC)

## Conversion of Units of Time

 60 seconds = 1 minute 60 minutes = 1 hour(3600 seconds) 24 hours = 1 day(86400 seconds) 7 days = 1 week 2 weeks = 1 fortnight 30 days(or) 31 days = 1 month 365 days = 1 year 366 days = 1 leap year 10 years = 1 decade 100 years = 1 century 1000 years = 10 Centuries (or) 1 millennium

Now let us see the example by applying the above concept to understand this topic better.
Example 1:

Convert 385 seconds into minutes

Solution :

To solve this problem let us use the conversion 1 minute = 60 seconds. Now we have to split this 385 as 360 + 25. There is 6 minutes in 360 seconds and we have to leave 25 seconds as it is.

Example 2:

Convert 245 seconds into minutes

Solution :

To solve this problem let us use the conversion 1 minute = 60 seconds. Now we have to split this 245 as 240 + 5. There is 4 minutes in 240 seconds and we have to leave 25 seconds as it is.
