Conversion formula

The conversion factor from feet per second to knots is 0.59248380129641, which means that 1 foot per second is equal to 0.59248380129641 knots:

1 ft/s = 0.59248380129641 kt

To convert 1821 feet per second into knots we have to multiply 1821 by the conversion factor in order to get the velocity amount from feet per second to knots. We can also form a simple proportion to calculate the result:

1 ft/s → 0.59248380129641 kt

1821 ft/s → V_(kt)

Solve the above proportion to obtain the velocity V in knots:

V_(kt) = 1821 ft/s × 0.59248380129641 kt

V_(kt) = 1078.9130021608 kt

The final result is:

1821 ft/s → 1078.9130021608 kt

We conclude that 1821 feet per second is equivalent to 1078.9130021608 knots:

1821 feet per second = 1078.9130021608 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.00092685879027992 × 1821 feet per second.

Another way is saying that 1821 feet per second is equal to 1 ÷ 0.00092685879027992 knots.

Approximate result

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

1821 ft/s ≅ 1078.913 kt

An alternative is also that one knot is approximately zero point zero zero one times one thousand eight hundred twenty-one feet per second.
