## Conversion formula

The conversion factor from days to seconds is 86400, which means that 1 day is equal to 86400 seconds:

1 d = 86400 s

To convert 9 days into seconds we have to multiply 9 by the conversion factor in order to get the time amount from days to seconds. We can also form a simple proportion to calculate the result:

1 d → 86400 s

9 d → T(s)

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

T(s) = 9 d × 86400 s

T(s) = 777600 s

The final result is:

9 d → 777600 s

We conclude that 9 days is equivalent to 777600 seconds:

9 days = 777600 seconds

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 second is equal to 1.2860082304527E-6 × 9 days.

Another way is saying that 9 days is equal to 1 ÷ 1.2860082304527E-6 seconds.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that nine days is approximately seven hundred seventy-seven thousand six hundred seconds:

9 d ≅ 777600 s

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