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 3 days into hours we have to multiply 3 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
3 d → T(hr)
Solve the above proportion to obtain the time T in hours:
T(hr) = 3 d × 24 hr
T(hr) = 72 hr
The final result is:
3 d → 72 hr
We conclude that 3 days is equivalent to 72 hours:
3 days = 72 hours
