## 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 21.6 knots into miles per hour we have to multiply 21.6 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

21.6 kt → V(mph)

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

V(mph) = 21.6 kt × 1.1507794480225 mph

V(mph) = 24.856836077287 mph

The final result is:

21.6 kt → 24.856836077287 mph

We conclude that 21.6 knots is equivalent to 24.856836077287 miles per hour:
