Conversion formula

The conversion factor from feet per second to knots is 0.59248380129641, which means that 1 foot per second is equal to 0.59248380129641 knots:

1 ft/s = 0.59248380129641 kt

To convert 228.5 feet per second into knots we have to multiply 228.5 by the conversion factor in order to get the velocity amount from feet per second to knots. We can also form a simple proportion to calculate the result:

1 ft/s → 0.59248380129641 kt

228.5 ft/s → V_(kt)

Solve the above proportion to obtain the velocity V in knots:

V_(kt) = 228.5 ft/s × 0.59248380129641 kt

V_(kt) = 135.38254859623 kt

The final result is:

228.5 ft/s → 135.38254859623 kt

We conclude that 228.5 feet per second is equivalent to 135.38254859623 knots:

228.5 feet per second = 135.38254859623 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0073864763986859 × 228.5 feet per second.

Another way is saying that 228.5 feet per second is equal to 1 ÷ 0.0073864763986859 knots.

Approximate result

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

228.5 ft/s ≅ 135.383 kt

An alternative is also that one knot is approximately zero point zero zero seven times two hundred twenty-eight point five feet per second.
