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 knots into miles per hour we have to multiply 15 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 kt → V(mph)

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

V(mph) = 15 kt × 1.1507794480225 mph

V(mph) = 17.261691720338 mph

The final result is:

15 kt → 17.261691720338 mph

We conclude that 15 knots is equivalent to 17.261691720338 miles per hour:
