2 Cases to Convert Hours and Minutes to Decimal in Excel

We will discuss this article for 2 cases. One case is converting hours to decimal and another is converting minutes to decimal. For each case, we will show 3 different ways to convert the time value into decimal.


Case 1: Convert Hours to Decimal in Excel

In the first case, we will convert the hour’s value to decimal. As previously said, we will demonstrate three distinct methods for converting hours to decimal in this situation.

1.1 Converting Hours to Decimal in Excel with Simple Multiplication

In the first method, we will convert the hours to decimal values simply by multiplying the original value with 24. To demonstrate this method, we will use the following dataset. The dataset contains the values of six subjects as well as the duration of their class time. We can see the duration of the class in “h:mm: ss” format.

So, let’s see the steps to convert hours to decimal values by using simple multiplication.

STEPS:

  • Firstly, select cell D5. Insert the following in that cell:
=C5*24

  • Next, release the mouse click.
  • So, we can see the converted values of hours into decimal values in cells (D5:D10).

  • Thirdly, we will convert the decimal value into an integer value with the INT function. To do this select cell E5 and insert the following formula:
=INT(D5)

  • Next, press Enter. This action converts the decimal value “1.33” minutes into an integer value “1”.

  • Again, select cell E5. Make the plus (+) sign visible by moving the mouse cursor at the bottom right corner of that cell.

  • Then, click on the plus (+) sign and drag the Fill Handle down to cell E10 or you can do this by double-clicking on the plus (+).

  • Lastly, we can see the converted integer values cells (E5:E10).


1.2 Apply CONVERT Function in Excel

In Microsoft Excel, the CONVERT function converts the system of measurement of a number. In this method, we will use the CONVERT function to convert hours to decimal in excel. We will use the same dataset that we have used in the previous example.

Now, let’s see the steps regarding this method.

STEPS:

  • First, select cell D5. Insert the following formula in that cell:
=CONVERT(C5,"day","hr")

Apply CONVERT Function in Excel

  • Press Enter. This action returns the value of hours of cell C5 in decimal which is “1.33”.

  • Release the mouse button now.
  • Finally, the operation above duplicates cell D5’s formula to the other cells. As a result, all the time values in the duration column convert into decimal values.

  • Then, we’ll turn the decimal value into an integer value. To accomplish this, go to cell E5 and type in the formula:
=INT(D5)

  • Press Enter. This command changes the decimal value of “1.33” minutes to an integer value of 1.

  • Now, move the mouse cursor to the bottom right corner of cell E5 to make the plus (+) sign visible.

  • After that, either double-click on the plus (+) sign or click on the plus(+) sign and drag the Fill Handle tool down to cell E10.

  • Finally, we get the integer values of hours in cells (E5:E10).


1.3 Use Combination of HOUR, MINUTE, and SECOND Functions

The excel HOUR, MINUTE, and SECOND functions separate the matching time portion from a timestamp. In this example, we will convert hours to decimals using these functions. To demonstrate the method we will continue with the same dataset.

Use Combination of HOUR, MINUTE, and SECOND Functions

Let’s take a look at the steps to perform this method.

STEPS:

  • In the beginning, select cell D5 and insert the following formula:
=HOUR(C5)+MINUTE(C5)/60+SECOND(C5)/3600

Use Combination of HOUR, MINUTE, and SECOND Functions

  • Press Enter. We get the converted decimal value of cell C5 in cell D5.

Use Combination of HOUR, MINUTE, and SECOND Functions

  • Next, we will select cell D5 and move the mouse cursor to the bottom right corner. It will make a plus (+) sign seeable like the following image.

Use Combination of HOUR, MINUTE, and SECOND Functions

  • Then, tap on the plus (+) sign and drag the Fill Handle downwards to cell D10 to replicate cell D5’s formula into other cells. You can also get the same result by double-clicking the plus (+).

Use Combination of HOUR, MINUTE, and SECOND Functions

  • Now, free the mouse click.
  • So, the above command copies the formula of cell D5 to the other cells. We can see the converted decimal values of hours in cells (D5:D10).

Use Combination of HOUR, MINUTE, and SECOND Functions

Here, in the formula, the “MINUTE(C5)/60” part converts minutes into hours. The part “SECOND(C5)/3600” converts seconds into hours.

  • Then, to convert the decimal values into integer values select cell E5 and insert the formula:
=INT(D5)

  • Hit Enter. So we can see the decimal value of “1.33” minutes is converted to an integer value of “1” hour.

  • After that, to make the plus (+) sign visible, move the mouse cursor to the bottom right corner of cell E5 after selecting that cell.

  • Then, double-click on the plus (+) sign or click on the plus (+) sign and drag the Fill Handle down to cell E10.

  • Finally, the integer values of hours in cells are obtained (E5:E10).

2.1 Insert Simple Multiplication to Convert Minutes to Decimal

In this method, we will convert minutes to decimals by multiplying the original value by 1440. We will use the following dataset to explain this example. Here the duration of classes is given in “h:mm: ss” format.

Insert Simple Multiplication to Convert Minutes to Decimal

So, let’s see the steps regarding this method.

STEPS:

  • Firstly, select cell D5. Insert the following formula in that cell:
=C5*1440

  • Press the Enter So, the decimal value of “80.42” minutes has been transformed to an integer value of “80” minutes.

  • So then, move the mouse cursor to the bottom right corner of cell E5 after selecting that cell to make the plus (+) sign available.

  • Afterward, drag the Fill Handle down to cell E10 by tapping on the plus (+) sign or do double-click on the plus (+) sign to obtain the same result.

  • Finally, the integer hours values in cells are determined in cells (E5:E10).


2.2 Use CONVERT Function to Convert Minutes to Decimal in Excel

The CONVERT function in Microsoft Excel converts a number’s measurement system. We’ll use the CONVERT function in Excel to convert minutes to decimal in this method. We’re going to use the same dataset as in the last example.

  • Press Enter, As a result, the decimal value “80.42” minutes have been converted to an integer “80” minutes.

  • Again, move the mouse cursor to the bottom right corner of that cell to make the plus (+) sign available after selecting cell E5.

  • After that, double-click on the plus (+) sign or click on the plus (+) sign to drag the Fill Handle down to cell E10.

  • At last, the integer hours values are calculated in the cells (E5:E10).


2.3 Combine HOUR, MINUTE, and SECOND Functions

Multiplying hours by 60 and dividing seconds by the same number is another approach to finding the number of minutes. We will explain this process with the same dataset that we used in the previous example.

Combine HOUR, MINUTE, and SECOND Functions

Let’s see the step-by-step guide to do this method.

STEPS:

  • In the beginning, select cell D5 and insert the following formula:
=HOUR(C5)*60+MINUTE(C5)+SECOND(C5)/60

Combine HOUR, MINUTE, and SECOND Functions

  • Now press Enter. This command returns the minutes value in decimal which is “80.42”.

  • After this drag, the Fill Handle downwards to cell D10 by clicking the plus (+) We may also perform the same thing by double-clicking on the plus (+) sign.

Combine HOUR, MINUTE, and SECOND Functions

  • Now free the mouse. click
  • As a result, using the instruction above, the formula from cell D5 is duplicated to all other cells. We can see the converted decimal hours in the cells(D5:D10).

Combine HOUR, MINUTE, and SECOND Functions

Here, in the formula, the part “HOUR(C5)*60” converts hours into minutes. The part “SECOND(C5)/60” converts seconds into minutes.

  • Additionally, in cell E5, write the following formula to convert the decimal number to an integer value:
=INT(D5)

  • Now, hit Enter. As a consequence, “80.42” minutes have been changed to an integer of “80”.

  • Now select cell E5 and drop the mouse cursor to the bottom right corner of that cell to display the plus (+).

  • After that, move the Fill Handle down to cell E10 by clicking on the plus (+) we can do this also by double-clicking on the plus (+) sign.

  • Finally, the integer minute values are calculated in cells (E5:E10).
