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 251 feet per second into knots we have to multiply 251 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

251 ft/s → V_(kt)

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

V_(kt) = 251 ft/s × 0.59248380129641 kt

V_(kt) = 148.7134341254 kt

The final result is:

251 ft/s → 148.7134341254 kt

We conclude that 251 feet per second is equivalent to 148.7134341254 knots:

251 feet per second = 148.7134341254 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0067243420601583 × 251 feet per second.

Another way is saying that 251 feet per second is equal to 1 ÷ 0.0067243420601583 knots.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that two hundred fifty-one feet per second is approximately one hundred forty-eight point seven one three knots:

251 ft/s ≅ 148.713 kt

An alternative is also that one knot is approximately zero point zero zero seven times two hundred fifty-one feet per second.
