Conversion formula

The conversion factor from knots to kilometers per hour is 1.8519999999969, which means that 1 knot is equal to 1.8519999999969 kilometers per hour:

1 kt = 1.8519999999969 km/h

To convert 438 knots into kilometers per hour we have to multiply 438 by the conversion factor in order to get the velocity amount from knots to kilometers per hour. We can also form a simple proportion to calculate the result:

1 kt → 1.8519999999969 km/h

438 kt → V(km/h)

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

V(km/h) = 438 kt × 1.8519999999969 km/h

V(km/h) = 811.17599999865 km/h

The final result is:

438 kt → 811.17599999865 km/h

We conclude that 438 knots is equivalent to 811.17599999865 kilometers per hour:

438 knots = 811.17599999865 kilometers per hour

Alternative conversion
