1 hour equals 3600 seconds
Converting 1 hour to seconds results in 3600 seconds because there are 60 seconds in a minute and 60 minutes in an hour, so multiplying these gives the total seconds in an hour.
Conversion of 1 hour to seconds
1 hour is equal to 3600 seconds because 1 hour is composed of 60 minutes, and each minute contains 60 seconds. So, to get seconds from hours, you multiply the number of hours by 60 (minutes per hour) and then by 60 (seconds per minute), resulting in 60 × 60 = 3600 seconds.

Conversion Formula
The formula to convert hours to seconds is “seconds = hours × 60 × 60”. This works because each hour contains 60 minutes, and each minute contains 60 seconds. Multiplying hours by 60 gives minutes, then multiplying those minutes by 60 gets seconds. For example, 2 hours: 2 × 60 = 120 minutes, 120 × 60 = 7200 seconds.
Conversion Example
- Converting 2 hours:
- Start with 2 hours.
- Multiply 2 by 60 to get minutes: 2 × 60 = 120 minutes.
- Then multiply 120 by 60 to get seconds: 120 × 60 = 7200 seconds.
- Converting 0.5 hours:
- Start with 0.5 hours.
- Multiply 0.5 by 60 to get minutes: 0.5 × 60 = 30 minutes.
- Multiply 30 by 60 to get seconds: 30 × 60 = 1800 seconds.
- Converting 3.75 hours:
- Start with 3.75 hours.
- Multiply 3.75 by 60 to get minutes: 3.75 × 60 = 225 minutes.
- Multiply 225 by 60 to get seconds: 225 × 60 = 13500 seconds.
