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 401 knots into feet per second we have to multiply 401 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

401 kt → V_(ft/s)

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

V_(ft/s) = 401 kt × 1.6878098570997 ft/s

V_(ft/s) = 676.81175269699 ft/s

The final result is:

401 kt → 676.81175269699 ft/s

We conclude that 401 knots is equivalent to 676.81175269699 feet per second:

401 knots = 676.81175269699 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 0.0014775157139561 × 401 knots.

Another way is saying that 401 knots is equal to 1 ÷ 0.0014775157139561 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 one knots is approximately six hundred seventy-six point eight one two feet per second:

401 kt ≅ 676.812 ft/s

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