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 420 knots into feet per second we have to multiply 420 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
420 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 420 kt × 1.6878098570997 ft/s
V(ft/s) = 708.88013998189 ft/s
The final result is:
420 kt → 708.88013998189 ft/s
We conclude that 420 knots is equivalent to 708.88013998189 feet per second:
420 knots = 708.88013998189 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 0.0014106757173724 × 420 knots.
Another way is saying that 420 knots is equal to 1 ÷ 0.0014106757173724 feet per second.
Approximate result
For practical purposes we can round our final result to an approximate numerical value. We can say that four hundred twenty knots is approximately seven hundred eight point eight eight feet per second:
420 kt ≅ 708.88 ft/s
An alternative is also that one foot per second is approximately zero point zero zero one times four hundred twenty knots.
