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.
14 Billion years
Approx 3.1688 quadrillion years. By comparison, the Universe is thought to have been in existence for only 14 billion years.
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.
441,796,964 seconds.
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
