## 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 7 days into hours we have to multiply 7 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

7 d → T(hr)

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

T(hr) = 7 d × 24 hr

T(hr) = 168 hr

The final result is:

7 d → 168 hr

We conclude that 7 days is equivalent to 168 hours:

7 days = 168 hours

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 hour is equal to 0.005952380952381 × 7 days.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that seven days is approximately one hundred sixty-eight hours:

7 d ≅ 168 hr

An alternative is also that one hour is approximately zero point zero zero six times seven days.
