## 5 Ways to Convert Time to Number in Excel

Suppose you have a list of time ranges. It contains the **Times to Convert into Numbers**.

Now, we’ll convert those times to numbers using various methods in Excel. So, without further delay, let’s jump into the approaches one by one.

### 1. Engaging Format Cells Option to Convert Time to Number in Excel

We can apply the **Format Cells** option to convert our times into numbers. Follow the steps below to understand this method comprehensively.

**📌**** Steps**

- At first, create a new column in the
**C4:C12**range. Give it a suitable header. In this case, we named it the**Number**column. - Secondly, copy cells in the
**C5:C12**range by pressing**CTRL+C**.

- Now, paste these into cell
**C5**.

- Then, go to the
**Home**tab. - After that, select the
**Number**group. - Next, click on the down arrow in the
**Number Format**box. - Finally, choose the
**General**format from the list.

- At this point, the times are showing as number values.

We can reduce the digits after the decimal to make it look nicer.

- Initially, select cells in the
**C5:C12**range. - Again, go to the
**Home**tab. - Then, select the
**Number**group. - After that, click several times on the
**Decrease Decimal**icon until you get your desired digits after the decimal.

- Finally, we converted the times into numbers. And they look like the one below.

### 2. Using TIMEVALUE Function to Convert Time to Number in Excel

An alternative way to do the same job is to use **the TIMEVALUE function**. Follow the steps below.

**📌**** Steps**

- At first, select cell
**C5**. - Then, write down the formula below and press
**ENTER**.

`=TEXT(B5,"H:MM:ss")`

Here, **B5** represents the time **8:45:12 AM**.

In this formula, we used **the TEXT function** to convert the time in cell **B5** into a text string.

- Next, use the
**Fill Handle**tool to get the formula in the remaining lower cells.

- After that, select cell
**D5**and type in the formula below. - Then, press the
**ENTER**key.

`=TIMEVALUE(C5)`

Here, **C5** represents the text string **8:45:12** in cell **C5**.

Hence, we used **the TIMEVALUE function** here. This function takes a text string as input. Then, it returns the text string as a representation of time in decimal number format. The decimal value ranges from **0** to **0.99988426**, which corresponds to the hours between **0:00:00** (**12:00:00 AM**) and **23:59:59** (**11:59:59 PM**).

- Finally, the numbers look like the one below.

### 3. Applying Simple Arithmetic Formula

Also, we can assign simple arithmetic calculations. To solve this way, follow the steps carefully.

**📌**** Steps**

- At the very beginning, select cell
**C6**. - Then, write down the formula below and press
**ENTER**.

`=B6*24`

Here, **B6** serves as the cell reference for the first ** Time** in the list.

In the formula above, we multiplied

**B6**by

**24**as this is the number of

**hours**in a

**day**.

- At this point, go to the
**Home**tab. - After that, select the
**Number**group. - Next, click on the down arrow in the
**Number Format**box. - Finally, choose the
**Number**format from the list.

- Instantly, it looks like the one below.
- Finally, the time is converted into the number of hours.

- After that, use the
**Fill Handle**tool to get the full results.

- Then, select cell D6 and paste down the formula below.

`=B6*1440`

Here, we multiplied the cell reference of **B6** with **1440** as it’s the number of **minutes** in a whole day.

- After that, press
**ENTER**.

- Similarly, we can get the number in seconds.
- At first, select cell
**F6**. - Then, write down the formula below and press
**ENTER**.

`=B6*86400`

In such a situation, we multiplied the value of cell **B6** by **86400**. Because it’s the number of **seconds** in a whole **day**.

- At last, we converted the
**Time**into the**Number**of**Hours**,**Minutes,**and**Seconds**.

### 4. Implementing HOUR, MINUTE, and SECOND Functions

We can use multiple Excel functions at a time to solve this problem. Follow our steps below.

**📌**** Steps**

- Primarily, select cell
**C6**and put down the formula below.

`=HOUR(B6)+MINUTE(B6)/60+SECOND(B6)/3600`

Here, **B6** serves as the cell reference for the first ** Time** in the list.

**⚙️**** Formula Breakdown**

**HOUR(B6)****⟶****The HOUR function**returns the hour of a time value. Here,**B6**is the**serial_number**argument. It is the time containing the hour we want to find.**Output****⟶****8**

**MINUTE(B6)/60****⟶****The MINUTE function**returns the minutes of a time value. Then, we divided the output by**60**. Because we’re calculating the number of hours. Thus, we know that one hour equals sixty minutes.**Output****⟶****0.75**

**SECOND(B6)/3600****⟶****The Second function**returns the seconds of a time value. The second is given as an integer in the range 0 to 59. Thus we divided the output by**3600**to get it in hours.**Output****⟶****0**

- After that, press the
**ENTER**key.

- Again, select cell
**D6**and put down the formula below.

`=HOUR(B6)*60+MINUTE(B6)+SECOND(B6)/60`

Here, we’re calculating the number in minutes. So, we have to multiply the output of **the HOUR function** by **60**. This converts the value from hours to minutes.

- Similarly, we can convert the
**Time**into a number of**Seconds**. - At first, select cell
**E6**and paste the formula below.

`=HOUR(B6)*3600+MINUTE(B6)*60+SECOND(B6)`

- Then, press
**ENTER**.

- Finally, we converted the
**Time**into**Numbers**of**Hours**,**Minutes***,*and**Seconds**.

### 5. Employing CONVERT Function

A very well substitute to convert time into numbers in Excel is to use **the CONVERT function**. Follow the steps below.

**📌**** Steps**

- Firstly, select cell
**C6**and write down the formula below.

`=CONVERT(B6,"day","hr")`

Here, **B6** represents the time **8:45:12 AM**.

In this function, the last two arguments are **from_unit** and **to_unit**. **From_unit** is the unit of the input. Whereas, **to_unit** is the unit for the result. In this case, the **day** is the **from_unit** and **hr** is the **to_unit**. This function converts the time of the **day** to just **hours**.

- Similarly, convert the
to*Time*and*Minutes*also using the same function. Just change the*Seconds***to_unit**to**mn**and**sec**respectively.

## Conversion of Time Difference to Numbers

Let’s say, we have a dataset containing the **Start Time** in **Column C**and **End Time** in **Column D **of a certain work. Also, **Column B** holds the **Names** of the individuals who have done the job.

- From the dataset, we calculated the time difference first.
- At first, select cell
**E5**and paste down the formula below.

`=D5-C5`

Here, **C5** and **D5** serve as cell references for the first *Start* and *End Time*. These are **7:40 AM** and **12:25 PM**.

- Then, press the
**ENTER**key.

- At this point, copy cells in the
**E5:E10**range. - Then, go to the
**Home**tab. - After that, select
**Paste**in the ribbon as per the image below. - Later, select cell
**F5**. - Finally, paste the copied data as
**Values (V)**.

- Then, change the cell format as we have done before in
**Method 3**.

- Finally, the time difference is shown as numbers on the sheet.
