To convert 8.7 hours into minutes we have to multiply 8.7 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

8.7 hr → T(min)

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

T(min) = 8.7 hr × 60 min

T(min) = 522 min

The final result is:

8.7 hr → 522 min

We conclude that 8.7 hours is equivalent to 522 minutes:

8.7 hours = 522 minutes
