How many minutes are in a billion years? - Answers

The first step is to figure out how many minutes are in a year. There are 365.25 days in a year (approximately) - the 0.25 is an approximation of leap years. We're skipping "leap seconds" just to keep this simple. In one day, there are 24 hours, and there are 60 minutes per hour. Therefore, there are 24*60 or 1,440 minutes in one day. 1,440 minutes per day times 365.25 days per year equals 525,960 minutes per year. All you do is add nine zeros to the end of this to multiply by a billion years, resulting in 525,960,000,000,000 minutes in a billion years. For bonus points, that reads as "five hundred twenty five trillion, nine hundred sixty billion minutes".
