## Conversion formula

The conversion factor from hours to seconds is 3600, which means that 1 hour is equal to 3600 seconds:

1 hr = 3600 s

To convert 2.5 hours into seconds we have to multiply 2.5 by the conversion factor in order to get the time amount from hours to seconds. We can also form a simple proportion to calculate the result:

1 hr → 3600 s

2.5 hr → T_{(s)}

Solve the above proportion to obtain the time *T* in seconds:

T_{(s)} = 2.5 hr × 3600 s

T_{(s)} = 9000 s

The final result is:

2.5 hr → 9000 s

We conclude that **2.5 hours is equivalent to 9000 seconds**:

2.5 hours = 9000 seconds

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case **1 second is equal to 0.00011111111111111 × 2.5 hours**.

Another way is saying that *2.5 hours is equal to 1 ÷ 0.00011111111111111 seconds*.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that **two point five hours is approximately nine thousand seconds**:

2.5 hr ≅ 9000 s

An alternative is also that *one second is approximately zero times two point five hours*.
