## Conversion formula

The conversion factor from days to hours is 24, which means that 1 day is equal to 24 hours:

1 d = 24 hr

To convert 31.1 days into hours we have to multiply 31.1 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

31.1 d → T(hr)

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

T(hr) = 31.1 d × 24 hr

T(hr) = 746.4 hr

The final result is:

31.1 d → 746.4 hr

We conclude that 31.1 days is equivalent to 746.4 hours:

31.1 days = 746.4 hours ## Alternative conversion
