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 42.8 knots into feet per second we have to multiply 42.8 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

42.8 kt → V_(ft/s)

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

V_(ft/s) = 42.8 kt × 1.6878098570997 ft/s

V_(ft/s) = 72.238261883869 ft/s

The final result is:

42.8 kt → 72.238261883869 ft/s

We conclude that 42.8 knots is equivalent to 72.238261883869 feet per second:

42.8 knots = 72.238261883869 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 0.013843079469542 × 42.8 knots.

Another way is saying that 42.8 knots is equal to 1 ÷ 0.013843079469542 feet per second.

Approximate result

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

42.8 kt ≅ 72.238 ft/s

An alternative is also that one foot per second is approximately zero point zero one four times forty-two point eight knots.
