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 2.5 knots into feet per second we have to multiply 2.5 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
2.5 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 2.5 kt × 1.6878098570997 ft/s
V(ft/s) = 4.2195246427493 ft/s
The final result is:
2.5 kt → 4.2195246427493 ft/s
We conclude that 2.5 knots is equivalent to 4.2195246427493 feet per second:
2.5 knots = 4.2195246427493 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 0.23699352051856 × 2.5 knots.
Another way is saying that 2.5 knots is equal to 1 ÷ 0.23699352051856 feet per second.
Approximate result
For practical purposes we can round our final result to an approximate numerical value. We can say that two point five knots is approximately four point two two feet per second:
2.5 kt ≅ 4.22 ft/s
An alternative is also that one foot per second is approximately zero point two three seven times two point five knots.
