## 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 0.9 hours into seconds we have to multiply 0.9 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

0.9 hr → T(s)

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

T(s) = 0.9 hr × 3600 s

T(s) = 3240 s

The final result is:

0.9 hr → 3240 s

We conclude that 0.9 hours is equivalent to 3240 seconds:

0.9 hours = 3240 seconds ## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 second is equal to 0.00030864197530864 × 0.9 hours.

Another way is saying that 0.9 hours is equal to 1 ÷ 0.00030864197530864 seconds.

## Approximate result

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

0.9 hr ≅ 3240 s

An alternative is also that one second is approximately zero times zero point nine hours.
