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 8420 knots into feet per second we have to multiply 8420 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

8420 kt → V_(ft/s)

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

V_(ft/s) = 8420 kt × 1.6878098570997 ft/s

V_(ft/s) = 14211.35899678 ft/s

The final result is:

8420 kt → 14211.35899678 ft/s

We conclude that 8420 knots is equivalent to 14211.35899678 feet per second:

8420 knots = 14211.35899678 feet per second

Alternative conversion
