## 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 21.2 days into hours we have to multiply 21.2 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

21.2 d → T(hr)

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

T(hr) = 21.2 d × 24 hr

T(hr) = 508.8 hr

The final result is:

21.2 d → 508.8 hr

We conclude that 21.2 days is equivalent to 508.8 hours:

21.2 days = 508.8 hours

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 hour is equal to 0.0019654088050314 × 21.2 days.

## Approximate result

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

21.2 d ≅ 508.8 hr

An alternative is also that one hour is approximately zero point zero zero two times twenty-one point two days.
