## 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 10.4 days into seconds we have to multiply 10.4 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

10.4 d → T(s)

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

T(s) = 10.4 d × 86400 s

T(s) = 898560 s

The final result is:

10.4 d → 898560 s

We conclude that 10.4 days is equivalent to 898560 seconds:

10.4 days = 898560 seconds

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 second is equal to 1.1128917378917E-6 × 10.4 days.

Another way is saying that 10.4 days is equal to 1 ÷ 1.1128917378917E-6 seconds.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that ten point four days is approximately eight hundred ninety-eight thousand five hundred sixty seconds:

10.4 d ≅ 898560 s

An alternative is also that one second is approximately zero times ten point four days.
