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 9 days into hours we have to multiply 9 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
9 d → T(hr)
Solve the above proportion to obtain the time T in hours:
T(hr) = 9 d × 24 hr
T(hr) = 216 hr
The final result is:
9 d → 216 hr
We conclude that 9 days is equivalent to 216 hours:
9 days = 216 hours
