## 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 15 hours into minutes we have to multiply 15 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

15 hr → T(min)

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

T(min) = 15 hr × 60 min

T(min) = 900 min

The final result is:

15 hr → 900 min

We conclude that 15 hours is equivalent to 900 minutes:

15 hours = 900 minutes

## Alternative conversion
