## 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 81 knots into meters per second we have to multiply 81 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

81 kt → V(m/s)

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

V(m/s) = 81 kt × 0.514444444444 m/s

V(m/s) = 41.669999999964 m/s

The final result is:

81 kt → 41.669999999964 m/s

We conclude that 81 knots is equivalent to 41.669999999964 meters per second:

81 knots = 41.669999999964 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 0.023998080153608 × 81 knots.

Another way is saying that 81 knots is equal to 1 ÷ 0.023998080153608 meters per second.

## Approximate result

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

81 kt ≅ 41.67 m/s

An alternative is also that one meter per second is approximately zero point zero two four times eighty-one knots.
