How to go from hours to seconds

From hours to seconds is quite easy. First of all, we must remember that:

1 hour = 3,600 seconds

From this data, we can convert any number of hours to this smaller unit of time by simply performing a multiplication. Let's see it with a example, in which we will spend 3 hours to seconds:

3 hours x 3,600 = 10,800 seconds

Very easy, isn't it? What if we are given 2 hours and 30 minutes? In this case, we are going to convert the hours to seconds on one side and the minutes on the other.

2 hours x 3,600 = 7,200 seconds

30 minutes x 60 = 1,800 seconds

Finally, we add both amounts to obtain the total figure:

2 hours and 30 minutes = 7,200 seconds + 1,800 seconds = 9,000 seconds
