Conversion formula

The conversion factor from feet per second to knots is 0.59248380129641, which means that 1 foot per second is equal to 0.59248380129641 knots:

1 ft/s = 0.59248380129641 kt

To convert 1688 feet per second into knots we have to multiply 1688 by the conversion factor in order to get the velocity amount from feet per second to knots. We can also form a simple proportion to calculate the result:

1 ft/s → 0.59248380129641 kt

1688 ft/s → V_(kt)

Solve the above proportion to obtain the velocity V in knots:

V_(kt) = 1688 ft/s × 0.59248380129641 kt

V_(kt) = 1000.1126565883 kt

The final result is:

1688 ft/s → 1000.1126565883 kt

We conclude that 1688 feet per second is equivalent to 1000.1126565883 knots:

1688 feet per second = 1000.1126565883 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.00099988735610174 × 1688 feet per second.

Another way is saying that 1688 feet per second is equal to 1 ÷ 0.00099988735610174 knots.

Approximate result

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

1688 ft/s ≅ 1000.113 kt

An alternative is also that one knot is approximately zero point zero zero one times one thousand six hundred eighty-eight feet per second.
