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 17.8 knots into feet per second we have to multiply 17.8 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

17.8 kt → V_(ft/s)

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

V_(ft/s) = 17.8 kt × 1.6878098570997 ft/s

V_(ft/s) = 30.043015456375 ft/s

The final result is:

17.8 kt → 30.043015456375 ft/s

We conclude that 17.8 knots is equivalent to 30.043015456375 feet per second:

17.8 knots = 30.043015456375 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 0.033285606814405 × 17.8 knots.

Another way is saying that 17.8 knots is equal to 1 ÷ 0.033285606814405 feet per second.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that seventeen point eight knots is approximately thirty point zero four three feet per second:

17.8 kt ≅ 30.043 ft/s

An alternative is also that one foot per second is approximately zero point zero three three times seventeen point eight knots.
