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 1638 feet per second into knots we have to multiply 1638 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

1638 ft/s → V_(kt)

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

V_(kt) = 1638 ft/s × 0.59248380129641 kt

V_(kt) = 970.48846652352 kt

The final result is:

1638 ft/s → 970.48846652352 kt

We conclude that 1638 feet per second is equivalent to 970.48846652352 knots:

1638 feet per second = 970.48846652352 knots

Alternative conversion
