Conversion formula

The conversion factor from knots to kilometers per hour is 1.8519999999969, which means that 1 knot is equal to 1.8519999999969 kilometers per hour:

1 kt = 1.8519999999969 km/h

To convert 521 knots into kilometers per hour we have to multiply 521 by the conversion factor in order to get the velocity amount from knots to kilometers per hour. We can also form a simple proportion to calculate the result:

1 kt → 1.8519999999969 km/h

521 kt → V_(km/h)

Solve the above proportion to obtain the velocity V in kilometers per hour:

V_(km/h) = 521 kt × 1.8519999999969 km/h

V_(km/h) = 964.89199999839 km/h

The final result is:

521 kt → 964.89199999839 km/h

We conclude that 521 knots is equivalent to 964.89199999839 kilometers per hour:

521 knots = 964.89199999839 kilometers per hour

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer per hour is equal to 0.0010363854193025 × 521 knots.

Another way is saying that 521 knots is equal to 1 ÷ 0.0010363854193025 kilometers per hour.

Approximate result

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

521 kt ≅ 964.892 km/h

An alternative is also that one kilometer per hour is approximately zero point zero zero one times five hundred twenty-one knots.
