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 218 feet per second into knots we have to multiply 218 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

218 ft/s → V(kt)

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

V(kt) = 218 ft/s × 0.59248380129641 kt

V(kt) = 129.16146868262 kt

The final result is:

218 ft/s → 129.16146868262 kt

We conclude that 218 feet per second is equivalent to 129.16146868262 knots:

218 feet per second = 129.16146868262 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0077422470509162 × 218 feet per second.

Another way is saying that 218 feet per second is equal to 1 ÷ 0.0077422470509162 knots.

Approximate result

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

218 ft/s ≅ 129.161 kt

An alternative is also that one knot is approximately zero point zero zero eight times two hundred eighteen feet per second.
