To convert 680 days into hours we have to multiply 680 by the conversion factor in order to get the time amount from days to hours. We can also form a simple proportion to calculate the result:

1 d → 24 hr

680 d → T(hr)

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

T(hr) = 680 d × 24 hr

T(hr) = 16320 hr

The final result is:

680 d → 16320 hr

We conclude that 680 days is equivalent to 16320 hours:

680 days = 16320 hours
