## Conversion formula

The conversion factor from knots to meters per second is 0.514444444444, which means that 1 knot is equal to 0.514444444444 meters per second:

1 kt = 0.514444444444 m/s

To convert 21.5 knots into meters per second we have to multiply 21.5 by the conversion factor in order to get the velocity amount from knots to meters per second. We can also form a simple proportion to calculate the result:

1 kt → 0.514444444444 m/s

21.5 kt → V(m/s)

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

V(m/s) = 21.5 kt × 0.514444444444 m/s

V(m/s) = 11.060555555546 m/s

The final result is:

21.5 kt → 11.060555555546 m/s

We conclude that 21.5 knots is equivalent to 11.060555555546 meters per second:

21.5 knots = 11.060555555546 meters per second

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 meter per second is equal to 0.090411371741502 × 21.5 knots.

Another way is saying that 21.5 knots is equal to 1 ÷ 0.090411371741502 meters per second.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that twenty-one point five knots is approximately eleven point zero six one meters per second:

21.5 kt ≅ 11.061 m/s

An alternative is also that one meter per second is approximately zero point zero nine times twenty-one point five knots.
