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 421 feet per second into knots we have to multiply 421 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
421 ft/s → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 421 ft/s × 0.59248380129641 kt
V(kt) = 249.43568034579 kt
The final result is:
421 ft/s → 249.43568034579 kt
We conclude that 421 feet per second is equivalent to 249.43568034579 knots:
421 feet per second = 249.43568034579 knots
Alternative conversion
We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0040090495418046 × 421 feet per second.
Another way is saying that 421 feet per second is equal to 1 ÷ 0.0040090495418046 knots.
Approximate result
For practical purposes we can round our final result to an approximate numerical value. We can say that four hundred twenty-one feet per second is approximately two hundred forty-nine point four three six knots:
421 ft/s ≅ 249.436 kt
An alternative is also that one knot is approximately zero point zero zero four times four hundred twenty-one feet per second.
