Conversion Formula
The formula to convert hours to seconds is: seconds = hours × 3,600. This works because each hour contains exactly 3,600 seconds. By multiplying the number of hours by 3,600, you get the total seconds. For example, 2 hours: 2 × 3,600 = 7,200 seconds.
Conversion Example
- Convert 1 hour:
- 1 hour × 3,600 seconds/hour = 3,600 seconds.
- Convert 5 hours:
- 5 hours × 3,600 seconds/hour = 18,000 seconds.
- Convert 0.5 hours:
- 0.5 hours × 3,600 seconds/hour = 1,800 seconds.
- Convert 10 hours:
- 10 hours × 3,600 seconds/hour = 36,000 seconds.
- Convert -2 hours:
- -2 hours × 3,600 seconds/hour = -7,200 seconds.
