## 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

## How many seconds are there in a day?

Applying the knowledge we have seen in the previous point, we are going to **calculate how many seconds there are in a day**. We already know that this implies that we have to convert 24 hours to seconds so applying the above formula, we have that:

24 hours x 3,600 seconds = 86,400 seconds

## Convert hours to seconds with Excel

**Excel allows us to go from hours to seconds** instantly using the convert function as follows:

=CONVERT(C3; "hr"; "s")

With that expression written in a free cell of your spreadsheet, we are telling Excel to transform the number of hours we write in cell C3 to seconds. Of course, you can change the coordinates of that cell to point to the cell of your choice.

In this way, we will create our own **hours to seconds calculator** with Excel.

If we prefer, we can also write directly in the formula the **number of hours we want to spend in seconds**. In this case, the formula to write would be as follows:

=CONVERT(3; "hr"; "s")

In this second example, **Excel will take us three hours to seconds** automatically.
