## 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 646 knots into meters per second we have to multiply 646 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

646 kt → V(m/s)

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

V(m/s) = 646 kt × 0.514444444444 m/s

V(m/s) = 332.33111111082 m/s

The final result is:

646 kt → 332.33111111082 m/s

We conclude that 646 knots is equivalent to 332.33111111082 meters per second:

646 knots = 332.33111111082 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 0.003009047201923 × 646 knots.

Another way is saying that 646 knots is equal to 1 ÷ 0.003009047201923 meters per second.

## Approximate result

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

646 kt ≅ 332.331 m/s

An alternative is also that one meter per second is approximately zero point zero zero three times six hundred forty-six knots.
