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 221 knots into feet per second we have to multiply 221 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
221 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 221 kt × 1.6878098570997 ft/s
V(ft/s) = 373.00597841904 ft/s
The final result is:
221 kt → 373.00597841904 ft/s
We conclude that 221 knots is equivalent to 373.00597841904 feet per second:
221 knots = 373.00597841904 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 0.0026809221778118 × 221 knots.
Another way is saying that 221 knots is equal to 1 ÷ 0.0026809221778118 feet per second.
Approximate result
For practical purposes we can round our final result to an approximate numerical value. We can say that two hundred twenty-one knots is approximately three hundred seventy-three point zero zero six feet per second:
221 kt ≅ 373.006 ft/s
An alternative is also that one foot per second is approximately zero point zero zero three times two hundred twenty-one knots.
