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 628 knots into feet per second we have to multiply 628 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

628 kt → V_(ft/s)

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

V_(ft/s) = 628 kt × 1.6878098570997 ft/s

V_(ft/s) = 1059.9445902586 ft/s

The final result is:

628 kt → 1059.9445902586 ft/s

We conclude that 628 knots is equivalent to 1059.9445902586 feet per second:

628 knots = 1059.9445902586 feet per second

Alternative conversion
