## How to convert hours to seconds (hr to s)

There are 60 seconds in a minute and 60 minutes in an hour. To find out how many seconds are in an hour, you multiply the number of seconds in a minute (60) by the number of minutes in an hour (60): seconds = hours × 3,600.## Example Conversion

Let's take a look at an example. The step-by-step process to convert 3 hours to seconds is:

- Understand the conversion formula: s = hr × 3600
- Substitute the required value. In this case we substitute 3 for hr so the formula becomes: s = 3 × 3600
- Calculate the result using the provided values. In our example the result is: 3 × 3600 = 10800 s

In summary, 3 hours is equal to 10800 seconds.

## Converting seconds to hours

In order to convert the other way around i.e. seconds to hours, you would use the following formula: hr = s ÷ 3600. To convert seconds to hours first substitute the second value into the above formula, and then execute the calculation. If we wanted to calculate 1 second in hours we follow these steps:

hr = s ÷ 3600

hr = 1 ÷ 3600

hr = 0.000277777777777777777777777777778

Or in other words, 1 second is equal to 0.000277777777777777777777777777778 hours.
