To calculate the number of seconds in 18 years, you can use the following formula: 18 years × 365 days/year × 24 hours/day × 60 minutes/hour × 60 seconds/minute. This gives you approximately 567,648,000 seconds, not accounting for leap years. Including leap years, the total would be around 567,795,200 seconds if there are five leap years in that period.
