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 12.8 knots into feet per second we have to multiply 12.8 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

12.8 kt → V(ft/s)

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

V(ft/s) = 12.8 kt × 1.6878098570997 ft/s

V(ft/s) = 21.603966170877 ft/s

The final result is:

12.8 kt → 21.603966170877 ft/s

We conclude that 12.8 knots is equivalent to 21.603966170877 feet per second:

12.8 knots = 21.603966170877 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 0.046287796976282 × 12.8 knots.

Another way is saying that 12.8 knots is equal to 1 ÷ 0.046287796976282 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 eight knots is approximately twenty-one point six zero four feet per second:

12.8 kt ≅ 21.604 ft/s

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