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 685 knots into meters per second we have to multiply 685 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

685 kt → V_(m/s)

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

V_(m/s) = 685 kt × 0.514444444444 m/s

V_(m/s) = 352.39444444414 m/s

The final result is:

685 kt → 352.39444444414 m/s

We conclude that 685 knots is equivalent to 352.39444444414 meters per second:

685 knots = 352.39444444414 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 0.0028377291860471 × 685 knots.

Another way is saying that 685 knots is equal to 1 ÷ 0.0028377291860471 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-five knots is approximately three hundred fifty-two point three nine four meters per second:

685 kt ≅ 352.394 m/s

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