You can use the following formula to convert a time duration to seconds in Google Sheets:

**=VALUE(B2*24*3600)
**

This particular formula converts the time duration in cell B2 to seconds.

For example, if the time is **10:14:22** then the formula will convert this to **36862 **so that the time is represented as 36,862 seconds.

The following example shows how to use this formula in practice.

**Example: Convert Time to Seconds in Google Sheets**

Suppose we have the following dataset in Google Sheets that shows the number of hours, minutes, and seconds it took various athletes to finish a competition:

We can ensure that the values in the Duration column are formatted as durations by highlighting the range **B2:B11**, then clicking the **Format** tab, then clicking **Number**, then clicking **Duration**:

We can then use the following formula to convert the durations into seconds:

**=VALUE(B2*24*3600)**

We will type this formula into cell **C2** and then click and drag the formula down to each remaining cell in column C:

The new **Seconds **column displays the time in the **Duration** column as seconds.

For example:

- A duration of 10 hours, 14 minutes, and 22 seconds is converted to
**36,862**seconds. - A duration of 26 hours, 14 minutes, and 22 seconds is converted to
**94,462**seconds. - A duration of 13 hours, 30 minutes, and 0 seconds is converted to
**48,600**seconds.

And so on.

**Note**: This formula works because durations are stored as number of days in Google Sheets.

Thus, multiplying by 24 hours in a day and then by 3,600 seconds in an hour allows us to convert time durations to seconds.
