First assume that an average leap year is 365.25 days. This allows for every fourth year being a leap year. Strictly speaking that is not true because every centenary is not a leap year but then every 4-centenary is, etc. Besides, it is not clear what meaning could be attached to a "year" for much of the 14 billion years since the the sun is nowhere near that old and the earth existed for less than a quarter of the time.
Anyway, assuming 1 year = 365.25 days,
1 day = 24 hours
1 hour = 60 minutes
1 minute = 60 seconds
you get 14 billion years = 4.42*1017 or 442 quadrillion seconds.
4.41796964 x 1017 seconds.
60 seconds in one minute. 60 minutes/3600 seconds in one hour 24 hours/86400 seconds in one day (I'll use 365.24 days in a year) 365.24 days/31556736 seconds in one year 14 years/441794304 seconds in 14 years. There are ~441,794,304 seconds in 14 years.
441,796,964 seconds.
31556926 in a year x 14 years =441796964 seconds
Converting Seconds to MinutesIn order convert from seconds to minutes, you must divide the amount of seconds by 60In this case, 856/60=14.2666666...so you have 14 whole minutes.14x60=840856-840=16so you have a final answer of 14 minutes and 16 seconds.
4.41796964 x 1017 seconds.
To convert seconds to years, you need to divide the total number of seconds by the number of seconds in a year. There are 60 seconds in a minute, 60 minutes in an hour, and 24 hours in a day, which equals 86,400 seconds in a day. There are 365 days in a year, so there are 31,536,000 seconds in a year. Dividing 1,000,000,000,000,000,000,000 seconds by 31,536,000 seconds in a year gives you approximately 31,688,087 years.

To convert seconds to minutes divide them by 60 ....... 2954 ÷ 60 = 49.2333. Now we need to convert that remainder into seconds ....... 49 minutes multiplied by 60 = 2950 seconds Subtract 49 minutes from the full amount of seconds ....... 2954 - 2940 = 14 So 2954 seconds = 49 minutes and 14 seconds
31556926 in a year x 14 years =441796964 seconds
14 billion
It is almost as old as the Universe. I understand that is slightly less than 14 billion years.
This is mainly an extrapolation of the expansion of the Universe. That is to say, the Universe is expanding at such a rate that the galaxies (or the matter that didn't convert to galaxies yet) would have been very close together 13 or 14 billion years ago.
about 14 billion years old
