## 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 12.2 days into hours we have to multiply 12.2 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

12.2 d → T(hr)

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

T(hr) = 12.2 d × 24 hr

T(hr) = 292.8 hr

The final result is:

12.2 d → 292.8 hr

We conclude that 12.2 days is equivalent to 292.8 hours:

12.2 days = 292.8 hours
