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 990 knots into meters per second we have to multiply 990 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

990 kt → V_(m/s)

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

V_(m/s) = 990 kt × 0.514444444444 m/s

V_(m/s) = 509.29999999956 m/s

The final result is:

990 kt → 509.29999999956 m/s

We conclude that 990 knots is equivalent to 509.29999999956 meters per second:

990 knots = 509.29999999956 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 0.0019634792852952 × 990 knots.

Another way is saying that 990 knots is equal to 1 ÷ 0.0019634792852952 meters per second.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that nine hundred ninety knots is approximately five hundred nine point three meters per second:

990 kt ≅ 509.3 m/s

An alternative is also that one meter per second is approximately zero point zero zero two times nine hundred ninety knots.
