Each hour can be understood as a percentage of the total hours of the day.

  • 01:00 = 1/24
  • 02:00 = 2/24
  • 03:00 = 3/24
  • and so on.

The percentage can be used to find the seconds.

Example (15:00)

15:00 * 86400 = 54000

Fifteen hours equals 54000 seconds.

15:00 is 15/24 (0.625).

0.625 * 84600 = 54000

Multiply to get 86400

24 (hours) * 60 (minutes) * 60 (seconds) = 86400
