## Conversion formula

The conversion factor from hours to minutes is 60, which means that 1 hour is equal to 60 minutes:

1 hr = 60 min

To convert 8.5 hours into minutes we have to multiply 8.5 by the conversion factor in order to get the time amount from hours to minutes. We can also form a simple proportion to calculate the result:

1 hr → 60 min

8.5 hr → T(min)

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

T(min) = 8.5 hr × 60 min

T(min) = 510 min

The final result is:

8.5 hr → 510 min

We conclude that 8.5 hours is equivalent to 510 minutes:

8.5 hours = 510 minutes

## Alternative conversion
