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 knots into feet per second we have to multiply 840 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 kt → V_(ft/s)

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

V_(ft/s) = 840 kt × 1.6878098570997 ft/s

V_(ft/s) = 1417.7602799638 ft/s

The final result is:

840 kt → 1417.7602799638 ft/s

We conclude that 840 knots is equivalent to 1417.7602799638 feet per second:

840 knots = 1417.7602799638 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 0.0007053378586862 × 840 knots.

Another way is saying that 840 knots is equal to 1 ÷ 0.0007053378586862 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 knots is approximately one thousand four hundred seventeen point seven six feet per second:

840 kt ≅ 1417.76 ft/s

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