## Conversion formula

The conversion factor from minutes to seconds is 60, which means that 1 minute is equal to 60 seconds:

1 min = 60 s

To convert 309 minutes into seconds we have to multiply 309 by the conversion factor in order to get the time amount from minutes to seconds. We can also form a simple proportion to calculate the result:

1 min → 60 s

309 min → T(s)

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

T(s) = 309 min × 60 s

T(s) = 18540 s

The final result is:

309 min → 18540 s

We conclude that 309 minutes is equivalent to 18540 seconds:

309 minutes = 18540 seconds
