Enter the number of hours, minutes, and seconds into the calculator to determine the decimal equivalent.

Hours To Decimal Formula

The following formula is used to calculate the decimal equivalent of hours, minutes, and seconds.

D = H + (M/60) + (S/3600)

Variables:

  • D is the decimal equivalent of hours, minutes, and seconds
  • H is the number of hours
  • M is the number of minutes
  • S is the number of seconds

To calculate the decimal equivalent, add the number of hours to the quotient of the number of minutes divided by 60, and the quotient of the number of seconds divided by 3600.

What is a Hours To Decimal?

Hours to Decimal is a conversion method that changes time measured in hours and minutes into a decimal number. This is often used in timekeeping and payroll calculations where it’s easier to work with decimal numbers rather than minutes. For example, 1 hour and 30 minutes would be converted to 1.5 hours in decimal form.

How to Calculate Hours To Decimal?

The following steps outline how to calculate the Hours To Decimal using the given formula:


  1. First, determine the number of hours (H).
  2. Next, determine the number of minutes (M).
  3. Next, determine the number of seconds (S).
  4. Use the formula D = H + (M/60) + (S/3600) to calculate the decimal equivalent of hours, minutes, and seconds.
  5. Finally, calculate the Hours To Decimal.
  6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.
