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 621 knots into feet per second we have to multiply 621 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

621 kt → V_(ft/s)

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

V_(ft/s) = 621 kt × 1.6878098570997 ft/s

V_(ft/s) = 1048.1299212589 ft/s

The final result is:

621 kt → 1048.1299212589 ft/s

We conclude that 621 knots is equivalent to 1048.1299212589 feet per second:

621 knots = 1048.1299212589 feet per second

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 foot per second is equal to 0.00095408019532433 × 621 knots.

Another way is saying that 621 knots is equal to 1 ÷ 0.00095408019532433 feet per second.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that six hundred twenty-one knots is approximately one thousand forty-eight point one three feet per second:

621 kt ≅ 1048.13 ft/s

An alternative is also that one foot per second is approximately zero point zero zero one times six hundred twenty-one knots.
