conversion scale showing seconds and equivalent hours time values

The fastest way to convert seconds to hours is to use this formula:

hours = seconds ÷ 3,600

The time in hours is equal to the time in seconds divided by 3,600. Since there are 3,600 seconds in one hour, that's the conversion ratio used in the formula.

For example, here's how to convert 5,400 seconds to hours using the formula above.

5,400 sec = (5,400 ÷ 3,600) = 1.5 hr

How to Convert Seconds to Hours, Minutes & Seconds

The formula above can be used to find the hours in decimal form, but if you want to get hours, minutes and seconds, then follow these steps.

  • Divide the seconds by 3,600 to get the total hours. Then, use the number to the left of the decimal point as the number of hours.
  • Find the remaining seconds by multiplying the even hours found above by 3,600. Then, subtract that from the total seconds.
  • Divide the remaining seconds by 60 to get the total number of remaining minutes. Then, use the number to the left of the decimal point as the number of minutes.
  • Find the remaining seconds again by multiplying the even minutes found above by 60. Then, subtract that from the total seconds. This is the remaining seconds.
  • Put the even number of hours, minutes, and remaining seconds into the form HH:MM:SS.
