Assumption: This is not a leap year

#31536000#

#"which is the same as "3.1536xx10^7#

Number of days in a year are 365

Number of hours in a day is 24
So the number of hours in a years is #24xx365" ""hours"/"year"#

Number of minutes in an hour is 60
So the number of minutes in a year is #60xx24xx356" ""minutes"/"year"#

The number of seconds in a minute is 60
So the number of seconds in a year is:

#60xx60xx24xx356" ""seconds"/"year"#

#31536000#

#->3.1536xx10^7#
