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 6421 knots into feet per second we have to multiply 6421 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

6421 kt → V_(ft/s)

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

V_(ft/s) = 6421 kt × 1.6878098570997 ft/s

V_(ft/s) = 10837.427092437 ft/s

The final result is:

6421 kt → 10837.427092437 ft/s

We conclude that 6421 knots is equivalent to 10837.427092437 feet per second:

6421 knots = 10837.427092437 feet per second

Alternative conversion
