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 688 knots into meters per second we have to multiply 688 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

688 kt → V_(m/s)

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

V_(m/s) = 688 kt × 0.514444444444 m/s

V_(m/s) = 353.93777777747 m/s

The final result is:

688 kt → 353.93777777747 m/s

We conclude that 688 knots is equivalent to 353.93777777747 meters per second:

688 knots = 353.93777777747 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 0.0028253553669219 × 688 knots.

Another way is saying that 688 knots is equal to 1 ÷ 0.0028253553669219 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-eight knots is approximately three hundred fifty-three point nine three eight meters per second:

688 kt ≅ 353.938 m/s

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