Conversion Formula
The formula to convert hours to seconds is: seconds = hours * 3600. This works because each hour has 60 minutes, and each minute has 60 seconds, so multiplying hours by 60 times 60 gives the total seconds. For example, 2 hours: 2 * 60 * 60 = 7200 seconds.
Conversion Example
- Convert 2 hours:
- Start with 2 hours.
- Multiply 2 by 3600 (since 1 hour = 3600 seconds).
- 2 * 3600 = 7200 seconds.
- The answer is 7200 seconds.
- Convert 0.5 hours:
- Begin with 0.5 hours.
- Multiply 0.5 by 3600.
- 0.5 * 3600 = 1800 seconds.
- Result is 1800 seconds.
- Convert 5.75 hours:
- Start with 5.75 hours.
- Multiply 5.75 by 3600.
- 5.75 * 3600 = 20700 seconds.
- Answer is 20700 seconds.
