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 840.4 knots into feet per second we have to multiply 840.4 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

840.4 kt → V_(ft/s)

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

V_(ft/s) = 840.4 kt × 1.6878098570997 ft/s

V_(ft/s) = 1418.4354039066 ft/s

The final result is:

840.4 kt → 1418.4354039066 ft/s

We conclude that 840.4 knots is equivalent to 1418.4354039066 feet per second:

840.4 knots = 1418.4354039066 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 0.00070500214337983 × 840.4 knots.

Another way is saying that 840.4 knots is equal to 1 ÷ 0.00070500214337983 feet per second.

Approximate result

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

840.4 kt ≅ 1418.435 ft/s

An alternative is also that one foot per second is approximately zero point zero zero one times eight hundred forty point four knots.
