4 hours equal 14,400 seconds.
Since 1 hour consists of 3,600 seconds, multiplying 4 hours by 3,600 gives the total seconds: 4 × 3,600 = 14,400 seconds.
Conversion Formula
The formula to convert hours to seconds is simple: multiply the number of hours by 3,600 because there are 3,600 seconds in one hour. This works because 1 hour = 60 minutes, and each minute = 60 seconds. So, 1 hour = 60 × 60 = 3,600 seconds.
For example, if you have 4 hours, then 4 × 3,600 = 14,400 seconds. This step-by-step calculation confirms how many seconds are in a specific number of hours.
