## 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 6.4 days into hours we have to multiply 6.4 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

6.4 d → T(hr)

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

T(hr) = 6.4 d × 24 hr

T(hr) = 153.6 hr

The final result is:

6.4 d → 153.6 hr

We conclude that 6.4 days is equivalent to 153.6 hours:

6.4 days = 153.6 hours ## Alternative conversion
