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 820.9 knots into feet per second we have to multiply 820.9 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

820.9 kt → V_(ft/s)

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

V_(ft/s) = 820.9 kt × 1.6878098570997 ft/s

V_(ft/s) = 1385.5231116932 ft/s

The final result is:

820.9 kt → 1385.5231116932 ft/s

We conclude that 820.9 knots is equivalent to 1385.5231116932 feet per second:

820.9 knots = 1385.5231116932 feet per second

Alternative conversion
