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 40 knots into meters per second we have to multiply 40 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

40 kt → V_(m/s)

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

V_(m/s) = 40 kt × 0.514444444444 m/s

V_(m/s) = 20.57777777776 m/s

The final result is:

40 kt → 20.57777777776 m/s

We conclude that 40 knots is equivalent to 20.57777777776 meters per second:

40 knots = 20.57777777776 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 0.048596112311057 × 40 knots.

Another way is saying that 40 knots is equal to 1 ÷ 0.048596112311057 meters per second.

Approximate result

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

40 kt ≅ 20.578 m/s

An alternative is also that one meter per second is approximately zero point zero four nine times forty knots.
