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 647 knots into feet per second we have to multiply 647 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

647 kt → V_(ft/s)

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

V_(ft/s) = 647 kt × 1.6878098570997 ft/s

V_(ft/s) = 1092.0129775435 ft/s

The final result is:

647 kt → 1092.0129775435 ft/s

We conclude that 647 knots is equivalent to 1092.0129775435 feet per second:

647 knots = 1092.0129775435 feet per second

Alternative conversion
