To convert hours to seconds, multiply the number of hours by 3,600. This calculator does it instantly, and the result matches the same figure a timesheet, spreadsheet, or textbook calculation would give.

Quick answer: 0.5 hours = 1,800 seconds, 1 hour = 3,600 seconds, 2 hours = 7,200 seconds, and 8 hours = 28,800 seconds. Because the ratio between these two units is fixed, the conversion is exact for any value, whole or decimal.

Enter any hours value above and the seconds equivalent updates instantly. For example, 1 hour converts to 3,600 seconds.
