To convert 17.5 days into hours we have to multiply 17.5 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

17.5 d → T(hr)

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

T(hr) = 17.5 d × 24 hr

T(hr) = 420 hr

The final result is:

17.5 d → 420 hr

We conclude that 17.5 days is equivalent to 420 hours:
