The value of 13 weeks in seconds is 7862400 seconds
<h3>Conversion of weeks to seconds</h3>
In order to convert weeks to seconds, we will use the following conversion factor
1week = 7 days
13weeks = 91days
<u>Convert days to hours</u>
Since 24 hours = 1 day, then;
91 days = (91*24)
91 days = 2184 hours
Convert hours to seconds
1 hour = 3600secs
Hence 2184 hours = (2184*3600)
2184 hours = 78624000 seconds
Hence the value of 13 weeks in seconds is 7862400 seconds
