How many seconds is a billion years?

Answer 1

thirty one thousand years

* * * * *

Out by a factor of 1000! I would go for

31 years 259 days 1 hour 46 minutes and 40 seconds.

But that is based on each year being 365 days. Any 30+ year period will include leap years. Assuming each year averages 365.25 days (not strictly true since not every 100th year is a leap year), the above figure becomes:

31 years 251 days 7 hours 46 minutes and 40 seconds.

The answer to this question would depend on whether you use the U.S. Atomic clock or the Mayan observance of what a year is.

The U.S. Atomic clock states that the length of time in one year is 365.2420 days (plus or minus .0005 of a day).

According to the Mayans the length of one year is exactly 365.2422 days. Since the Mayans seem to be fastidious fanatical (Nit Pickers) and a little more specific than the atomic clock, I have chose to use their measure. This being said I have rounded off numbers to the one thousands place, most likely to the chagrin of the long lost Mayans.

60 seconds X 60 Minutes X 24 hours = 86,400 seconds in one day

84,600 seconds in a day X 365.2242 in one year = 31,556,926.08 S. in one year

1 Billion / by 31,556,926.08 seconds in one year = 31.6887643507857 years.

.6887643507857 % of one year = 251.5658 days.

.5658% of one day = 13.5792 hours.

.5792% of one hour = 41.4364 Minutes.

.4364% of one minute = 26.184 seconds.

Therefore. If my math is correct the length of one billion seconds comes out to, 31years, 10 months, 7 days, 13 hours, 41 minutes, and 26.184 seconds.

Answer 2

(1,000,000,000 years) x (365 days / 1 year) x (24 hours / 1 day) x (60 minutes / 1 hour) x (60 seconds / 1 minute) = 3.1536 x 10^16 seconds
