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 821 knots into meters per second we have to multiply 821 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

821 kt → V_(m/s)

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

V_(m/s) = 821 kt × 0.514444444444 m/s

V_(m/s) = 422.35888888852 m/s

The final result is:

821 kt → 422.35888888852 m/s

We conclude that 821 knots is equivalent to 422.35888888852 meters per second:

821 knots = 422.35888888852 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 0.0023676546801977 × 821 knots.

Another way is saying that 821 knots is equal to 1 ÷ 0.0023676546801977 meters per second.

Approximate result

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

821 kt ≅ 422.359 m/s

An alternative is also that one meter per second is approximately zero point zero zero two times eight hundred twenty-one knots.
