## 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 15.3 knots into miles per hour we have to multiply 15.3 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

15.3 kt → V(mph)

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

V(mph) = 15.3 kt × 1.1507794480225 mph

V(mph) = 17.606925554745 mph

The final result is:

15.3 kt → 17.606925554745 mph

We conclude that 15.3 knots is equivalent to 17.606925554745 miles per hour:
