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 638 knots into meters per second we have to multiply 638 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

638 kt → V(m/s)

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

V(m/s) = 638 kt × 0.514444444444 m/s

V(m/s) = 328.21555555527 m/s

The final result is:

638 kt → 328.21555555527 m/s

We conclude that 638 knots is equivalent to 328.21555555527 meters per second:

638 knots = 328.21555555527 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 0.0030467782013202 × 638 knots.

Another way is saying that 638 knots is equal to 1 ÷ 0.0030467782013202 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 thirty-eight knots is approximately three hundred twenty-eight point two one six meters per second:

638 kt ≅ 328.216 m/s

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