## 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 686 knots into meters per second we have to multiply 686 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

686 kt → V(m/s)

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

V(m/s) = 686 kt × 0.514444444444 m/s

V(m/s) = 352.90888888858 m/s

The final result is:

686 kt → 352.90888888858 m/s

We conclude that 686 knots is equivalent to 352.90888888858 meters per second:

686 knots = 352.90888888858 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 0.0028335925545806 × 686 knots.

Another way is saying that 686 knots is equal to 1 ÷ 0.0028335925545806 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 eighty-six knots is approximately three hundred fifty-two point nine zero nine meters per second:

686 kt ≅ 352.909 m/s

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