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 20.4 knots into miles per hour we have to multiply 20.4 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
20.4 kt → V(mph)
Solve the above proportion to obtain the velocity V in miles per hour:
V(mph) = 20.4 kt × 1.1507794480225 mph
V(mph) = 23.47590073966 mph
The final result is:
20.4 kt → 23.47590073966 mph
