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 231 knots into feet per second we have to multiply 231 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

231 kt → V_(ft/s)

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

V_(ft/s) = 231 kt × 1.6878098570997 ft/s

V_(ft/s) = 389.88407699004 ft/s

The final result is:

231 kt → 389.88407699004 ft/s

We conclude that 231 knots is equivalent to 389.88407699004 feet per second:

231 knots = 389.88407699004 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 0.0025648649406771 × 231 knots.

Another way is saying that 231 knots is equal to 1 ÷ 0.0025648649406771 feet per second.

Approximate result

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

231 kt ≅ 389.884 ft/s

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