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 811 knots into feet per second we have to multiply 811 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

811 kt → V_(ft/s)

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

V_(ft/s) = 811 kt × 1.6878098570997 ft/s

V_(ft/s) = 1368.8137941079 ft/s

The final result is:

811 kt → 1368.8137941079 ft/s

We conclude that 811 knots is equivalent to 1368.8137941079 feet per second:

811 knots = 1368.8137941079 feet per second

Alternative conversion
