16.5 trillion is 16,500,000,000,000 seconds. / 60 /60 /24 /365.25 = 522853.44 years
2,000,000,000/(365.25*24*60*60)=63.37 years
60*60*24*365.4*50=1,578,528,000
5*365.25*24*60*60 = 157788000s
1 hour = 3600 seconds 24 hours = 86400 seconds 1 year = 365.25 days So 1 year = 31557600 seconds so 999 years = 31526042400 seconds
You can approximate your age in seconds by multiplying the number of years old you are by 365 days, by 24 hours, by 60 minutes, and by 60 seconds.
There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, 365 days in a year, for 2012 years. Multiply all those numbers to convert from 2012 years to seconds and you get 63,450,432,000 seconds.
A minute is 60 seconds. 24 x 60 = 1440 seconds.
86,400 seconds.
Without accounting for leap years and such, we have 60 x 365 x 24 x 60 x 60 = 1892160000 seconds
at least 1,226,227,704 seconds = 60 seconds x 60 minutes x 24 hours x 365.242199 days x 40 years
