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 123.4 knots into miles per hour we have to multiply 123.4 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

123.4 kt → V_(mph)

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

V_(mph) = 123.4 kt × 1.1507794480225 mph

V_(mph) = 142.00618388598 mph

The final result is:

123.4 kt → 142.00618388598 mph

We conclude that 123.4 knots is equivalent to 142.00618388598 miles per hour:

123.4 knots = 142.00618388598 miles per hour
