Conversion formula

The conversion factor from knots to feet per second is 1.6878098570997, which means that 1 knot is equal to 1.6878098570997 feet per second:

1 kt = 1.6878098570997 ft/s

To convert 551 knots into feet per second we have to multiply 551 by the conversion factor in order to get the velocity amount from knots to feet per second. We can also form a simple proportion to calculate the result:

1 kt → 1.6878098570997 ft/s

551 kt → V_(ft/s)

Solve the above proportion to obtain the velocity V in feet per second:

V_(ft/s) = 551 kt × 1.6878098570997 ft/s

V_(ft/s) = 929.98323126196 ft/s

The final result is:

551 kt → 929.98323126196 ft/s

We conclude that 551 knots is equivalent to 929.98323126196 feet per second:

551 knots = 929.98323126196 feet per second
