## Introduction

Excel is an excellent tool for calculating hours from time data. However, Excel offers various ways to write time data, which can make calculating hours confusing and prone to errors. In this guide, we will explain how to calculate hours in Excel from time data with writing patterns. We will show you how to use Excel formulas and time formats to calculate hours accurately and efficiently.

## Step 1: Format the Time Cells

Before you start calculating hours in Excel, you need to format the time cells correctly. Select the cells that contain the time data and press Ctrl+1 to bring up the Format Cells dialog box. In the Number tab, select Time in the Category list and choose the time format that matches your data. For example, if your time data is in the format of hh:mm:ss, select 13:30:55.

## Step 2: Multiply Time by 24 to Get Hours

If your time data is in the format of hh:mm:ss or hh:mm, you can multiply it by 24 to get the hours. For example, if your time data is in the format of hh:mm:ss, use the formula =A124 in a blank cell to get the hours. If your time data is in the format of hh:mm, use the formula =A124/60 in a blank cell to get the hours.

## Step 3: Use the HOUR Function

If your time data is in the format of hh:mm:ss or hh:mm, you can use the HOUR function to extract the hours. For example, if your time data is in cell A1, use the formula =HOUR(A1) in a blank cell to get the hours.

## Step 4: Use the TIME Function

If your time data is in different cells for hours, minutes, and seconds, you can use the TIME function to combine them into one cell. For example, if your hours are in cell A1, minutes are in cell B1, and seconds are in cell C1, use the formula =TIME(A1,B1,C1) in a blank cell to get the total time. Then, use the formula =A1*24 in another blank cell to get the hours.

## Step 5: Use the ROUND Function

If your hours have decimal places that need to be rounded, use the ROUND function. For example, if your hours are in cell A1 and you want to round them to two decimal places, use the formula =ROUND(A1,2) in a blank cell.

## Step 6: Use the TRUNC Function

If your hours have decimal places that need to be truncated, use the TRUNC function. For example, if your hours are in cell A1 and you want to truncate them to two decimal places, use the formula =TRUNC(A1,2) in a blank cell.

## Step 7: Use the INT Function

If your hours have decimal places that need to be removed, use the INT function. For example, if your hours are in cell A1 and you want to remove the decimal places, use the formula =INT(A1) in a blank cell.

## Step 8: Use the SUM Function

If you want to add up a range of time data to get the total hours, use the SUM function. For example, if your time data is in cells A1 to A5, use the formula =SUM(A1:A5)*24 in a blank cell to get the total hours.

## Step 9: Use the AVERAGE Function

If you want to calculate the average hours of a range of time data, use the AVERAGE function. For example, if your time data is in cells A1 to A5, use the formula =AVERAGE(A1:A5)*24 in a blank cell to get the average hours.

## Step 10: Use the MAX Function

If you want to find the maximum hours of a range of time data, use the MAX function. For example, if your time data is in cells A1 to A5, use the formula =MAX(A1:A5)*24 in a blank cell to get the maximum hours.

## Step 11: Use the MIN Function

If you want to find the minimum hours of a range of time data, use the MIN function. For example, if your time data is in cells A1 to A5, use the formula =MIN(A1:A5)*24 in a blank cell to get the minimum hours.

## Step 12: Use the IF Function

If you want to calculate hours based on certain conditions, use the IF function. For example, if your time data is in cells A1 to A5 and you want to calculate the hours only for the data that is greater than 8 hours, use the formula =IF(A1>8,A1-8,0) in a blank cell to get the hours.

## Step 13: Use the NETWORKDAYS Function

If you want to calculate the working hours between two dates, use the NETWORKDAYS function. For example, if your start date is in cell A1, end date is in cell B1, and the working hours are from 9:00 AM to 5:00 PM, use the formula =NETWORKDAYS(A1,B1)*8 in a blank cell to get the working hours.

## Step 14: Use the MOD Function

If you want to calculate the remaining hours after dividing by a certain number of hours, use the MOD function. For example, if your total hours are in cell A1 and you want to calculate the remaining hours after dividing by 8 hours, use the formula =MOD(A1,8) in a blank cell to get the remaining hours.

## Step 15: Use the TEXT Function

If you want to display the hours in a specific format, use the TEXT function. For example, if your hours are in cell A1 and you want to display them in the format of hh:mm AM/PM, use the formula =TEXT(A1/24,"hh:mm AM/PM") in a blank cell.

## Step 16: Use the CONCATENATE Function

If you want to concatenate the hours, minutes, and seconds into one cell, use the CONCATENATE function. For example, if your hours are in cell A1, minutes are in cell B1, and seconds are in cell C1, use the formula =CONCATENATE(A1,":",B1,":",C1) in a blank cell.

## Step 17: Use the LEFT Function

If you want to extract the hours from a combined time data cell, use the LEFT function. For example, if your combined time data is in cell A1 and you want to extract the hours, use the formula =LEFT(A1,2) in a blank cell.
