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 421 meters per second into knots we have to multiply 421 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

421 m/s → V_(kt)

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

V_(kt) = 421 m/s × 1.9438444924423 kt

V_(kt) = 818.3585313182 kt

The final result is:

421 m/s → 818.3585313182 kt

We conclude that 421 meters per second is equivalent to 818.3585313182 knots:

421 meters per second = 818.3585313182 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.001221958300342 × 421 meters per second.

Another way is saying that 421 meters per second is equal to 1 ÷ 0.001221958300342 knots.

Approximate result

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

421 m/s ≅ 818.359 kt

An alternative is also that one knot is approximately zero point zero zero one times four hundred twenty-one meters per second.
