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 1221 knots into feet per second we have to multiply 1221 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

1221 kt → V_(ft/s)

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

V_(ft/s) = 1221 kt × 1.6878098570997 ft/s

V_(ft/s) = 2060.8158355188 ft/s

The final result is:

1221 kt → 2060.8158355188 ft/s

We conclude that 1221 knots is equivalent to 2060.8158355188 feet per second:

1221 knots = 2060.8158355188 feet per second

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 foot per second is equal to 0.00048524471850648 × 1221 knots.

Another way is saying that 1221 knots is equal to 1 ÷ 0.00048524471850648 feet per second.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that one thousand two hundred twenty-one knots is approximately two thousand sixty point eight one six feet per second:

1221 kt ≅ 2060.816 ft/s

An alternative is also that one foot per second is approximately zero times one thousand two hundred twenty-one knots.
