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 688 knots into kilometers per hour we have to multiply 688 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
688 kt → V(km/h)
Solve the above proportion to obtain the velocity V in kilometers per hour:
V(km/h) = 688 kt × 1.8519999999969 km/h
V(km/h) = 1274.1759999979 km/h
The final result is:
688 kt → 1274.1759999979 km/h
We conclude that 688 knots is equivalent to 1274.1759999979 kilometers per hour:
688 knots = 1274.1759999979 kilometers per hour
Alternative conversion
