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 687.7 knots into kilometers per hour we have to multiply 687.7 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
687.7 kt → V(km/h)
Solve the above proportion to obtain the velocity V in kilometers per hour:
V(km/h) = 687.7 kt × 1.8519999999969 km/h
V(km/h) = 1273.6203999979 km/h
The final result is:
687.7 kt → 1273.6203999979 km/h
We conclude that 687.7 knots is equivalent to 1273.6203999979 kilometers per hour:
687.7 knots = 1273.6203999979 kilometers per hour
Alternative conversion
