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 20 knots into miles per hour we have to multiply 20 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

20 kt → V_(mph)

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

V_(mph) = 20 kt × 1.1507794480225 mph

V_(mph) = 23.015588960451 mph

The final result is:

20 kt → 23.015588960451 mph

We conclude that 20 knots is equivalent to 23.015588960451 miles per hour:

20 knots = 23.015588960451 miles per hour
