How to Convert Time to Decimal Hours

Learning how to convert time to decimal is an essential skill for anyone who works with timesheets, payroll, or project management. When you convert time to decimal format, you transform hours and minutes into a single decimal number that's much easier to use in calculations. This guide will show you exactly how to convert time to decimal hours quickly and accurately.

The Formula to Convert Time to Decimal

To convert time to decimal, use this simple formula:

Decimal Hours = Hours + (Minutes ÷ 60) + (Seconds ÷ 3600)

This formula works because there are 60 minutes in an hour and 3600 seconds in an hour. When you divide minutes by 60, you get the decimal portion of an hour. For example, to convert time to decimal for 30 minutes, you calculate 30 ÷ 60 = 0.5 hours.

Step-by-Step: Convert Time to Decimal

Let's walk through how to convert time to decimal with a practical example. Say you worked 7 hours and 45 minutes:

  1. Start with the hours: 7 hours stays as 7
  2. Convert minutes to decimal: 45 ÷ 60 = 0.75
  3. Add them together: 7 + 0.75 = 7.75 decimal hours

Now you can easily multiply 7.75 by your hourly rate to calculate pay. This is why businesses prefer to convert time to decimal for payroll processing.
