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 221 knots into feet per second we have to multiply 221 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

221 kt → V(ft/s)

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

V(ft/s) = 221 kt × 1.6878098570997 ft/s

V(ft/s) = 373.00597841904 ft/s

The final result is:

221 kt → 373.00597841904 ft/s

We conclude that 221 knots is equivalent to 373.00597841904 feet per second:

221 knots = 373.00597841904 feet per second
