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 12.7 knots into feet per second we have to multiply 12.7 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

12.7 kt → V_(ft/s)

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

V_(ft/s) = 12.7 kt × 1.6878098570997 ft/s

V_(ft/s) = 21.435185185167 ft/s

The final result is:

12.7 kt → 21.435185185167 ft/s

We conclude that 12.7 knots is equivalent to 21.435185185167 feet per second:

12.7 knots = 21.435185185167 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 0.046652267818615 × 12.7 knots.

Another way is saying that 12.7 knots is equal to 1 ÷ 0.046652267818615 feet per second.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that twelve point seven knots is approximately twenty-one point four three five feet per second:

12.7 kt ≅ 21.435 ft/s

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