## How to Convert Seconds to Hours

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.

hours = (5,400 sec ÷ 3,600) = 1.5 hr

### How to Convert Seconds to Hours, Minutes & Seconds

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

- Divide the total seconds by 3,600 to get the total hours in decimal form. Then, use the number to the left of the decimal point as the number of whole hours.
- Find the remaining minutes by subtracting the whole hours from the total hours, then multiplying the result by 60. The number to the left of the decimal point is the number of whole minutes.
- Find the remaining seconds by subtracting the whole minutes from the remaining minutes found above, then multiplying the result by 60. The result is the number of seconds remaining.
- Finally, put the number of whole hours, minutes, and remaining seconds into the form HH:MM:SS where HH are the whole hours, MM are the whole minutes, and SS are the remaining seconds.

Seconds and hours are both units used to measure time. Keep reading to learn more about each unit of measure.
