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 400 feet per second into knots we have to multiply 400 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

400 ft/s → V_(kt)

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

V_(kt) = 400 ft/s × 0.59248380129641 kt

V_(kt) = 236.99352051856 kt

The final result is:

400 ft/s → 236.99352051856 kt

We conclude that 400 feet per second is equivalent to 236.99352051856 knots:

400 feet per second = 236.99352051856 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0042195246427493 × 400 feet per second.

Another way is saying that 400 feet per second is equal to 1 ÷ 0.0042195246427493 knots.

Approximate result

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

400 ft/s ≅ 236.994 kt

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