To convert 20 days into hours we have to multiply 20 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

20 d → T_(hr)

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

T_(hr) = 20 d × 24 hr

T_(hr) = 480 hr

The final result is:

20 d → 480 hr

We conclude that 20 days is equivalent to 480 hours:

20 days = 480 hours
