To convert 155 days into hours we have to multiply 155 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

155 d → T(hr)

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

T(hr) = 155 d × 24 hr

T(hr) = 3720 hr

The final result is:

155 d → 3720 hr

We conclude that 155 days is equivalent to 3720 hours:

155 days = 3720 hours
