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 221 feet per second into knots we have to multiply 221 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
221 ft/s → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 221 ft/s × 0.59248380129641 kt
V(kt) = 130.93892008651 kt
The final result is:
221 ft/s → 130.93892008651 kt
We conclude that 221 feet per second is equivalent to 130.93892008651 knots:
221 feet per second = 130.93892008651 knots
Alternative conversion
We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0076371486746594 × 221 feet per second.
Another way is saying that 221 feet per second is equal to 1 ÷ 0.0076371486746594 knots.
Approximate result
For practical purposes we can round our final result to an approximate numerical value. We can say that two hundred twenty-one feet per second is approximately one hundred thirty point nine three nine knots:
221 ft/s ≅ 130.939 kt
An alternative is also that one knot is approximately zero point zero zero eight times two hundred twenty-one feet per second.
