Do you need to convert time notation to decimal notation in Excel? This article will provide you with an easy guide to do so. Learn how you can use formulas and functions to convert your time into decimal notation quickly and accurately.
Knowing Excel Time Notation Basics
Understanding Excel Time Notation is essential for manipulating spreadsheets that contain dates and times without hassle! To help you out, here are five tips for mastering time in Excel.
 Distinguish 12hour and 24hour formats: Before noon is Ante Meridiem (AM) and after noon is Post Meridiem (PM) in a 12hour format. In 24hour military time, each hour is numbered from 0 to 23.
 Know how Excel stores time data: Internally, Excel assigns each date and time a unique serial number. For example, the value “1” represents midnight on January 1st, 1900. Every hour adds a fraction of a day to the integer part.
 Familiarize yourself with the TIME function: This allows you to create custom time values using hours, minutes, and seconds. For example, =TIME(10,30,0) represents 10:30 AM.
 Master elapsed times: Calculate the duration between two points in time by subtracting one timestamp from another or using the HOUR(), MINUTE() and SECOND() functions.
 Get comfortable converting timestamp formats: Practice converting timestamps between various formats such as military time to standard time without external tools or software.
By taking these steps, you’ll be able to confidently use numerical representation for time data and perform calculations with ease!
Understanding Time Formats in Excel

Familiarize yourself with the different time formats in Excel. These include “General,” “Long Date,” and “Short Date.”

Learn how Excel measures time. It’s based on the number of seconds since January 1, 1900. Therefore dates before this are represented by negative numbers.

To change the time format, select the cell/range then click ‘Formatting.’ Alternatively, use keyboard shortcuts like Ctrl+Shift+# or Ctrl+Shift+@.

Master formulas to manipulate time values. Excel treats them like numbers – making manipulation easier.
Time Formats are vital for accuracy and interpreting data sets. Without knowledge, you could spend time trying to input or interpret data. Don’t fall behind; master this key concept.
Now that you understand Time Formats in Excel, let’s move on to Conversion of Time Notation to Decimal Notation.
How to Convert Time Notation to Decimal Notation in Excel
Have you ever wondered how to convert time notation to decimal notation in Excel? It’s not hard. It can save you time and reduce stress when dealing with timebased data. This article will share some methods I have used.
 First, using the HOUR and MINUTE functions to make a decimal.
 Second, applying the TIMEVALUE function for conversion.
 Lastly, using the MOD function to convert to fractions of hours.
Let’s get started!
Utilizing the HOUR and MINUTE Functions
Get decimal notation from time values in Excel with the HOUR() and MINUTE() functions. Follow these 5 steps:
 Pick an empty cell for the result.
 In the formula bar, type “=HOUR()” plus the cell reference of your time value, in parentheses.
 After the closing parentheses, add “+MINUTE()/60” plus another set of parentheses with the same time value reference.
 Press Enter. You now have your decimal notation result.
 To make sure the result is a number, select the cell and use the Number Format dropdown in the Home toolbar to choose “Number”.
This method uses HOUR() and MINUTE() to get hours and minutes, then divides them by units of an hour (60 minutes). It also assumes no negative or fractional times, so your data must be uniform for accurate results.
This method saves processing time compared to manual conversion. Try it out!
Now let’s look at another useful tool – the TIMEVALUE Function.
Applying the TIMEVALUE Function
To use this function, start by selecting the cell where you want the decimal result to appear. Type =TIMEVALUE(“cell containing time notation”) in the cell. The TIMEVALUE function should be applied now.
Copy & paste the formula to other cells, if you have multiple cells with different time notations. You can also drag the formula cell to autoapply it.
Inputting time notations? Make sure they follow proper syntax (hours:minutes:seconds). Remove any extra spaces or characters.
Use the TIMEVALUE Function to quickly & easily convert time notations into decimal values without trouble. This is an important step in your Excel conversions! Use the TIMEVALUE Function precisely & accurately for future calculations.
Let’s talk about Making Use of the MOD Function, next.
Making Use of the MOD Function
The MOD function can be really useful when you’re working with time notation in Excel. Here’s a 5step guide on how to use it:
 Open your spreadsheet and select the cell where you want the decimal number.
 Enter the formula: If your time value is in hours, minutes and seconds format (e.g. 05:13:42) enter =MOD(A1*24, 24). If it’s in minutes and seconds format (e.g. 22:48), enter =MOD(A1/1440,1).
 Press Enter.
 You’ll get a decimal number as the result.
 Format it with Excel’s General or Number format.
The MOD function makes converting time notation to decimal notation super easy! Plus, it’s great for extracting the fractional part of division operations, and it works with negative and positive times without any errors. Decimals are also easy to work with in Excel, so it’s a great way to carry out calculations. Make sure you don’t miss out on using this awesome tool!

 Converting decimal notation to time notation
With this, you’ll be ready to master time notation in Excel and up your professional game.
How to Calculate Elapsed Time
Calculating elapsed time in Excel is easy! Follow these 6 steps:
 Format start and end times as times, not text. You may need to use the “TIMEVALUE” function for this.
 Subtract start time from end time for the total elapsed time.
 Use the custom format “[h]:mm:ss” to format the result.
 To convert to another unit, multiply by a conversion factor.
 Use “TRUNC” to round down to a whole number.
 Divide by 24 to convert back to decimal notation.
Elapsed time is essential for many projects, both business and personal. For example, tracking time spent on tasks helps you maintain accurate records. For larger projects, tracking time helps you stay on track and adjust priorities.
A company increased productivity by tracking work hours and comparing them to estimates. This resulted in improved efficiency throughout the company.
Finally, it’s important to understand the difference between two times when using date and time functions in Excel.
Determining the Difference Between Two Times
Determining the difference between two times can be very useful in Excel. Say you want to calculate an employee’s shift length, or how long it took to resolve a support ticket. Here’s the stepbystep:
 Enter start time in one cell and end time in another.
 In a third cell, subtract start time from end time using: =endstart.
 Result will appear in decimal format, e.g. 0.50 for half an hour or 2.25 for two hours and fifteen minutes.
 Divide decimal by 24 to get hours and minutes, using: =time/24.
 Format result as a time value. Right click on cell, go to “Format Cells” and select “Time”. Choose desired format from options available.
 Answer should now be displayed as hours and minutes instead of decimal format.
Determining time difference is crucial when dealing with data that needs total working hours, travel time or study duration calculations.
Fun Fact: Microsoft Excel first debuted on Macintosh computers in September 1985. It wasn’t until November that it was released for Windows machines.
Converting decimal to time notation is also helpful when working with Excel sheets. Transformation between the two notations might be needed.
