To convert 20.5 hours into minutes we have to multiply 20.5 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

20.5 hr → T(min)

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

T(min) = 20.5 hr × 60 min

T(min) = 1230 min

The final result is:

20.5 hr → 1230 min

We conclude that 20.5 hours is equivalent to 1230 minutes:
