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

**=HOUR(B2)+(MINUTE(B2)/60) + (SECOND(B2)/3600)
**

This particular formula converts the time in cell B2 to a decimal.

For example, if the time is **4:19:34** then the formula will convert this to **4.3261** so that the time is represented as 4.3261 hours.

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

**Example: Convert Time to Decimal 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 use the following formula to convert the durations into a decimal format:

**=HOUR(B2)+(MINUTE(B2)/60) + (SECOND(B2)/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 **Decimal** column displays the time in the **Duration** column as a decimal.

For example:

- A duration of 4 hours, 13 minutes, and 0 seconds is converted to
**4.2167**hours. - A duration of 13 hours, 30 minutes, and 15 seconds is converted to
**13.5041**hours. - A duration of 2 hours, 15 minutes, and 0 seconds is converted to
**2.25**hours.

And so on.

If you would instead like to display the durations in terms of number of days, you can divide the entire formula by 24:

**=(HOUR(B2)+(MINUTE(B2)/60) + (SECOND(B2)/3600)) / 24**

The following screenshot shows how to use this formula in practice:

The new **Decimal** column displays the time in the **Duration** column as a number of days.

For example:

- A duration of 4 hours, 13 minutes, and 0 seconds is converted to
**.1756**days. - A duration of 13 hours, 30 minutes, and 15 seconds is converted to
**.5626**days. - A duration of 2 hours, 15 minutes, and 0 seconds is converted to
**.09375**days.

And so on.
