To convert 730 days into hours we have to multiply 730 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

730 d → T(hr)

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

T(hr) = 730 d × 24 hr

T(hr) = 17520 hr

The final result is:

730 d → 17520 hr

We conclude that 730 days is equivalent to 17520 hours:

730 days = 17520 hours
