## 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 684 knots into meters per second we have to multiply 684 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

684 kt → V(m/s)

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

V(m/s) = 684 kt × 0.514444444444 m/s

V(m/s) = 351.8799999997 m/s

The final result is:

684 kt → 351.8799999997 m/s

We conclude that 684 knots is equivalent to 351.8799999997 meters per second:

684 knots = 351.8799999997 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 0.0028418779129273 × 684 knots.

Another way is saying that 684 knots is equal to 1 ÷ 0.0028418779129273 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-four knots is approximately three hundred fifty-one point eight eight meters per second:

684 kt ≅ 351.88 m/s

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