## How to Convert Seconds to Hours

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

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.
