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 300 knots into miles per hour we have to multiply 300 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

300 kt → V_(mph)

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

V_(mph) = 300 kt × 1.1507794480225 mph

V_(mph) = 345.23383440676 mph

The final result is:

300 kt → 345.23383440676 mph

We conclude that 300 knots is equivalent to 345.23383440676 miles per hour:

300 knots = 345.23383440676 miles per hour
