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 440 knots into miles per hour we have to multiply 440 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

440 kt → V_(mph)

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

V_(mph) = 440 kt × 1.1507794480225 mph

V_(mph) = 506.34295712992 mph

The final result is:

440 kt → 506.34295712992 mph

We conclude that 440 knots is equivalent to 506.34295712992 miles per hour:
