## Conversion formula

The conversion factor from knots to miles per hour is 1.1507794480225, which means that 1 knot is equal to 1.1507794480225 miles per hour:

1 kt = 1.1507794480225 mph

To convert 28.5 knots into miles per hour we have to multiply 28.5 by the conversion factor in order to get the velocity amount from knots to miles per hour. We can also form a simple proportion to calculate the result:

1 kt → 1.1507794480225 mph

28.5 kt → V(mph)

Solve the above proportion to obtain the velocity V in miles per hour:

V(mph) = 28.5 kt × 1.1507794480225 mph

V(mph) = 32.797214268643 mph

The final result is:

28.5 kt → 32.797214268643 mph

We conclude that 28.5 knots is equivalent to 32.797214268643 miles per hour:
