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 1821 knots into feet per second we have to multiply 1821 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

1821 kt → V_(ft/s)

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

V_(ft/s) = 1821 kt × 1.6878098570997 ft/s

V_(ft/s) = 3073.5017497786 ft/s

The final result is:

1821 kt → 3073.5017497786 ft/s

We conclude that 1821 knots is equivalent to 3073.5017497786 feet per second:

1821 knots = 3073.5017497786 feet per second
