Conversion formula

The conversion factor from meters per second to knots is 1.9438444924423, which means that 1 meter per second is equal to 1.9438444924423 knots:

1 m/s = 1.9438444924423 kt

To convert 640.8 meters per second into knots we have to multiply 640.8 by the conversion factor in order to get the velocity amount from meters per second to knots. We can also form a simple proportion to calculate the result:

1 m/s → 1.9438444924423 kt

640.8 m/s → V_(kt)

Solve the above proportion to obtain the velocity V in knots:

V_(kt) = 640.8 m/s × 1.9438444924423 kt

V_(kt) = 1245.615550757 kt

The final result is:

640.8 m/s → 1245.615550757 kt

We conclude that 640.8 meters per second is equivalent to 1245.615550757 knots:

640.8 meters per second = 1245.615550757 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.00080281592453808 × 640.8 meters per second.

Another way is saying that 640.8 meters per second is equal to 1 ÷ 0.00080281592453808 knots.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that six hundred forty point eight meters per second is approximately one thousand two hundred forty-five point six one six knots:

640.8 m/s ≅ 1245.616 kt

An alternative is also that one knot is approximately zero point zero zero one times six hundred forty point eight meters per second.
