**Converting hours and minutes** **to minutes** can be useful in various situations, especially when you need to perform calculations or make comparisons based on time.

For example, if you need to calculate the total duration of two time intervals expressed in hours and minutes, it might be easier to convert them to minutes first and then add them up.

Similarly, if you want to compare the duration of two events that have different lengths expressed in **hours and minutes, converting them to a common unit** (i.e., minutes) can make the comparison more straightforward.

In general, converting hours and minutes to minutes can simplify time-related calculations and make them more intuitive.

**1 hour = 60 minutes = 3600 seconds =1/24 day**

One hour is equivalent to 60 minutes, which is equivalent to 3,600 seconds. Additionally, one day has 24 hours, so one hour is also equal to 1/24th of a day.

## How to Converting Hours and Minutes to Minutes

### method1: arithmetic calculations

To convert hours to minutes in Excel, you can simply multiply the value in hours by 60.

Here’s an example formula:

**= hours * 60**

For instance, if you want to convert 2.5 hours to minutes, enter this formula into a cell:

**= 2.5 * 60**

The result will be 150, which means that 2.5 hours is equal to 150 minutes.

### method2: HOUR and MINUTE functions

To convert hours and minutes represented in the format of “hh:mm” to minutes, you can use the following formula in Excel:

**=HOUR(A1)*60+MINUTE(A1)**

Where A1 is the cell containing the time value in the “hh:mm” format.

For example, if you have the value “12:20” in cell A1, you would use the following formula:

**=HOUR(A1)*60+MINUTE(A1)**

The result will be:

740

So, 12 hours and 20 minutes is equivalent to 740 minutes.

## How to Convert Hours and Minutes and Seconds to Seconds

To convert hours, minutes, and seconds to seconds in Excel, you can use either arithmetic calculations or the CONVERT function.

**Using arithmetic**calculation: To convert hours, minutes, and seconds to seconds using arithmetic calculations, you simply need to multiply the hours by 3600, the minutes by 60, and then add the seconds:

**= (hours * 3600) + (minutes * 60) + seconds**

For example, if you have 2 hours, 30 minutes, and 45 seconds, the formula would be:

**= (2 * 3600) + (30 * 60) + 45**

which would give you a result of 9,045 seconds.

**Using the CONVERT function**: The CONVERT function can also be used to convert hours, minutes, and seconds to seconds. Here’s how to do it:

**=CONVERT("hour","second",hours) + CONVERT("minute","second",minutes) + seconds**

For example, if you have 2 hours, 30 minutes, and 45 seconds, the formula would be:

**=CONVERT("hour","second",2) + CONVERT("minute","second",30) + 45**

which would also give you a result of 9,045 seconds.

How to Convert Minutes to Hours

To convert minutes to hours in Excel, you can divide the number of minutes by 60. Here’s an example:

Let’s say you have 120 minutes that you want to convert to hours. You would use the following formula:

**=120/60**

The result in this case would be 2, as there are 2 hours in 120 minutes.

You can also use the INT function to round down the result to the nearest integer.

For example:

**=INT(120/60)**

This formula would give you a result of 2 as well.

If you want to include any remaining minutes beyond whole hours, you can use the MOD function to calculate them.

For example:

**=INT(120/60) & " hours, " & MOD(120,60) & " minutes"**

This formula would give you a result of “2 hours, 0 minutes”.

The MOD function calculates the remainder after dividing 120 by 60, which is 0 in this case, meaning there are no remaining minutes beyond whole hours.

## How to Convert second to Minutes

To convert seconds to minutes in Excel, you can divide the number of seconds by 60. Here’s an example:

Let’s say you have 180 seconds that you want to convert to minutes. You would use the following formula:

**=180/60**

The result in this case would be 3, as there are 3 minutes in 180 seconds.

You can also use the INT function to round down the result to the nearest integer.

For example:

**=INT(180/60)**

This formula would give you a result of 3 as well.

If you want to include any remaining seconds beyond whole minutes, you can add the MOD function to the formula.

For example:

**=INT(180/60) & " minutes, " & MOD(180,60) & " seconds"**

This formula would give you a result of “3 minutes, 0 seconds”. The MOD function calculates the remainder after dividing 180 by 60, which is 0 in this case, meaning there are no remaining seconds beyond whole minutes.

## How to Convert seconds to hours

To convert seconds to hours in Excel, you can divide the number of seconds by 3600. Here’s an example:

Let’s say you have 10,800 seconds that you want to convert to hours. You would use the following formula:

**=10800/3600**

The result in this case would be 3, as there are 3 hours in 10,800 seconds.

You can also use the INT function to round down the result to the nearest integer.

For example:

**=INT(10800/3600)**

This formula would give you a result of 3 as well.

If you want to include any remaining minutes and/or seconds beyond whole hours, you can use the MOD function to calculate them.

For example:

**=INT(10800/3600) & " hours, " & INT(MOD(10800,3600)/60) & " minutes, " & MOD(10800,60) & " seconds"**

This formula would give you a result of “3 hours, 0 minutes, 0 seconds”.

The MOD function calculates the remainder after dividing 10,800 by 3600, which is 0 in this case, meaning there are no remaining minutes or seconds beyond whole hours.

## Converting hh:mm:ss time format to hours

Converting hh:mm:ss time format to hours is a common requirement in Excel when working with time-based data. The following examples demonstrate how to perform this conversion using various methods.

### Method 1: Using the TIMEVALUE function

The TIMEVALUE function converts a text string that represents a time into a serial number that Excel recognizes as a time.

To convert time in hh:mm:ss format to hours, you can use the **TIMEVALUE function** along with the mathematical operator ‘*’ and the number 24, which represents the number of hours in a day.

Assume that cell A1 contains the time value in hh:mm:ss format. In cell B1, enter the following formula:

**=TIMEVALUE(A1)*24**

This formula converts the time in cell A1 to a decimal value representing the number of hours and displays the result in cell B1.

### Method 2: Using the HOUR, MINUTE and SECOND functions

You can also use the HOUR, MINUTE and SECOND functions to extract the hour, minute and second components from the time value in hh:mm:ss format and then convert them to hours.

This method requires three formulas instead of one, but it may be more intuitive for some users.

Assume that cell A1 contains the time value in hh:mm:ss format. In cell B1, enter the following formula:

**=HOUR(A1)+MINUTE(A1)/60+SECOND(A1)/3600**

This formula uses the HOUR function to extract the number of hours, the MINUTE function to extract the number of minutes (which is divided by 60 to convert it to hours), and the SECOND function to extract the number of seconds (which is divided by 3600 to convert it to hours).

The three values are added together to give the total number of hours, which is displayed in cell B1.

Both methods will give you the same result but use different approaches. Choose the one that works best for your specific needs and preferences.
