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 250 knots into feet per second we have to multiply 250 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

250 kt → V_(ft/s)

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

V_(ft/s) = 250 kt × 1.6878098570997 ft/s

V_(ft/s) = 421.95246427493 ft/s

The final result is:

250 kt → 421.95246427493 ft/s

We conclude that 250 knots is equivalent to 421.95246427493 feet per second:

250 knots = 421.95246427493 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 0.0023699352051856 × 250 knots.

Another way is saying that 250 knots is equal to 1 ÷ 0.0023699352051856 feet per second.

Approximate result

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

250 kt ≅ 421.952 ft/s

An alternative is also that one foot per second is approximately zero point zero zero two times two hundred fifty knots.
