## 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 645 knots into meters per second we have to multiply 645 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

645 kt → V(m/s)

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

V(m/s) = 645 kt × 0.514444444444 m/s

V(m/s) = 331.81666666638 m/s

The final result is:

645 kt → 331.81666666638 m/s

We conclude that 645 knots is equivalent to 331.81666666638 meters per second:

645 knots = 331.81666666638 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 0.0030137123913834 × 645 knots.

Another way is saying that 645 knots is equal to 1 ÷ 0.0030137123913834 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 forty-five knots is approximately three hundred thirty-one point eight one seven meters per second:

645 kt ≅ 331.817 m/s

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