To convert 31.7 days into hours we have to multiply 31.7 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

31.7 d → T_(hr)

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

T_(hr) = 31.7 d × 24 hr

T_(hr) = 760.8 hr

The final result is:

31.7 d → 760.8 hr

We conclude that 31.7 days is equivalent to 760.8 hours:

31.7 days = 760.8 hours
