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 380 knots into feet per second we have to multiply 380 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

380 kt → V_(ft/s)

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

V_(ft/s) = 380 kt × 1.6878098570997 ft/s

V_(ft/s) = 641.3677456979 ft/s

The final result is:

380 kt → 641.3677456979 ft/s

We conclude that 380 knots is equivalent to 641.3677456979 feet per second:

380 knots = 641.3677456979 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 0.0015591678981484 × 380 knots.

Another way is saying that 380 knots is equal to 1 ÷ 0.0015591678981484 feet per second.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that three hundred eighty knots is approximately six hundred forty-one point three six eight feet per second:

380 kt ≅ 641.368 ft/s

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