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 420 feet per second into knots we have to multiply 420 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
420 ft/s → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 420 ft/s × 0.59248380129641 kt
V(kt) = 248.84319654449 kt
The final result is:
420 ft/s → 248.84319654449 kt
We conclude that 420 feet per second is equivalent to 248.84319654449 knots:
420 feet per second = 248.84319654449 knots
Alternative conversion
We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0040185948978565 × 420 feet per second.
Another way is saying that 420 feet per second is equal to 1 ÷ 0.0040185948978565 knots.
Approximate result
For practical purposes we can round our final result to an approximate numerical value. We can say that four hundred twenty feet per second is approximately two hundred forty-eight point eight four three knots:
420 ft/s ≅ 248.843 kt
An alternative is also that one knot is approximately zero point zero zero four times four hundred twenty feet per second.
