How many seconds in 1000000000 years?

Answer 1

To calculate the number of seconds in 1,000,000,000 years, we need to convert years to seconds. There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and approximately 365.25 days in a year (accounting for leap years). Therefore, the calculation would be: 1,000,000,000 years x 365.25 days/year x 24 hours/day x 60 minutes/hour x 60 seconds/minute = approximately 3.15 x 10^16 seconds in 1,000,000,000 years.

Answer 2

There are, roughly, pi times 10 million seconds in a year (the actual number is 31,556,926, but "pi times 10 million" is close and easier to remember). So just multiply that by that large number of years, and there's your answer.

So 1,000,000,000 years equals 3.1556926 × 1016 seconds.
