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 491 knots into feet per second we have to multiply 491 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

491 kt → V_(ft/s)

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

V_(ft/s) = 491 kt × 1.6878098570997 ft/s

V_(ft/s) = 828.71463983597 ft/s

The final result is:

491 kt → 828.71463983597 ft/s

We conclude that 491 knots is equivalent to 828.71463983597 feet per second:
